It is still early, and there is wide spread in the models, so please take any predictions made in the next 24 hours with a substantial degree of caution.
Hurricane Isaias is currently a messy cat 1 system just north of Haiti and east of Cuba. In the next 48 hours, it will most likely pass Cuba and turn north towards the east coast of Florida or the Bahamas. After that, it is likely to head up the east coast but models dIverge significantly after 48 hours.
We can expect Isaias to arrive at our latitude between Tues and Wed as a strong trop storm or a cat 1 hurricane based on the current model runs. The storm is slightly more likely to pass just offshore than on land but cannot rule out either at this time. Expect there to be some effect on the area, although what and how bad are still very much up in the air.
although what and how bad are still very much up in the air.
I see what you did there.
We just spent a lot of money removing a few very old, large, dead or dying trees from our property. I'm slightly less concerned about a tropical storm landfall than I was.
Family member is in Key West. Any idea of how much of a hit they might take? I think they were beyond stupid to go in the first place considering that there is a freakin pandemic going on . They said that if they get evacuated to Miami they might just keep driving and come back to NJ

As of now, they should be fine. Models have largely kept it curving up the east coast around a stout Bermuda high.
Then several days of interesting weather, with thunderstorms possible tomorrow and Monday, and Isaias on Tuesday. I'll have more details on Isaias later this morning, but for now suffice to say we can expect a very rainy day Tuesday but not likely hurricane winds.
Isaias looks absolutely horrible right now — in a good way. Shear and dry air are doing quite a number on it. The severe weather setup tomorrow in central/eastern PA/south central NY looks far more interesting at the moment.
WxNut, can you elaborate on the first part of your post-- does that mean Isiaiiaiaias is weakening for South Florida/Palm Beach County? Debating putting up the storm shutters.

Tropical cyclones that take on this evolution are often tough to accurately get a feel for. The storm is being negatively impacted by wind shear and dry air, which has caused it to weaken substantially. A healthy tropical cyclone is one in which the center of the circulation is closed off to the environment around it (think of a hurricane that has a small, circular eye). When the circulation is not closed off, it can ingest dry air which can hamper its intensification. That’s exactly what appears to be happening here.
So the challenge now is determining how that’s gonna impact this storm. If the circulation is weaker it is more likely to impact Florida, but of course as a weaker storm. Tbh I’m not particularly concerned about wind impacts in Florida with this one, but the thing about hurricane intensity is it’s notoriously difficult to forecast. To be safe maybe throw up the shutters, but I don’t see this one being a monster by any means.
WxNut, can you elaborate on the first part of your post-- does that mean Isiaiiaiaias is weakening for South Florida/Palm Beach County? Debating putting up the storm shutters.
That having been said, if Florida does see an impact it will be close to Palm Beach County. And while it’s still a storm to be taken seriously, it will likely be a glancing blow by a cat 1 hurricane/strong tropical storm. https://www.nhc.noaa.gov/graphics_at4.shtml?start#contents
Thanks so much! The a.m. reports seemed to indicate weaker wind than had been predicted last night, but it wasn't as clear as your explanation. Going to split the difference: closing the easy accordion shutters, and skipping the ones that require hanging panels. Fingers crossed.
So far, it's a beautiful sunny, breezy morning here.
Note that WxNut posted while I was writing this, so excuse please the partial redundancy.
Key takeaways for this update:
1. Forecast track and timing is still shifting from model run to model run.
2. Current guidance has Isaias passing either through or near NJ on Tuesday as a tropical storm.
3. Timing is still very uncertain. It is possible that there will be some heavy rain from the system as early as Monday night, and a late as early Wednesday morning, but the main storm is more likely to be a 4 - 6 hour period Tuesday afternoon and/or evening.
4. The main threats for Isaias are heavy rain and localized flooding. As of now, we might see anywhere from 3 - 6 inches of rain over a roughly 24 hour period.
5. No, I'm not sure how to pronounce it either.
Isaias remains a slow-moving cat 1 hurricane at this time over the Bahamas. The storm is more compact now but still messy in shape and structure. It is struggling with dry air and contrary wind conditions as it approaches Florida.
There is a fairly significant difference in the forecast, in part depending on whether Isaias makes landfall on Florida or not, although this is more an issue for North Carolina than NJ. The models differ both between the major models and from run to run. The American GFS model is more westerly and faster, with the PRE Monday night worth about an inch and the main event Tuesday afternoon and evening. The Euro is about 12 hours slower and more to the east. The GFS has a total of 4 - 5 inches of rain, while the Euro only shows 3 - 3.5 inches.
There are a variety of storms (both tropical and winter) that are coastal runners -- that is, they start in the tropics or off the southeast US coast and run up the coast. These storms are of a variety of different types but they share a challenge in forecasting for our area in that, as they run north, small changes in their track can have large impacts on how they affect our immediate area. Isaias, for example, is likely to be a fairly compact storm when it reaches our area; could be only 50 miles across for the main portion. This means a very small shift in the track can have very significant effect on the impact on any specific location.
Also, the effects of the storm are different on the east and west (seaward and landward) sides. On the eastern side of Isaias, wind and storm surge will be significant factors. On the western side, rain is most likely to be the most significant factor. At this time Isaias is more likely to pass east of us (putting us on the western, landward, side) so the forecast is more focused on rain. Since Isaias is so compact, this means that within the NY metro area, both sets of effects are likely to occur, with Long Island more likely to see the wind.
Another fun thing the models are showing is a PRE (Predecessor Rain Effect). This would be an additional inch or two of rain before the storm hits. The PRE is not consistent in all the models, and the location is also shifting from run to run.

Thanks for mentioning this Max, this is a really important thing from a hydrology point of view. A lot of research has gone into flood forecasting and found that one of the important variables in predicting flood intensity is antecedent soil conditions, specifically soil moisture. If there's precip immediately before Isaias that causes soil to be saturated, it will greatly increase the amount of runoff into rivers and streams when the precip from Isaias hits.

Yes, it's important. On the other hand, there is capacity in all the dams and reservoirs so any flooding would be localized road and small stream, not river systems.
Forecast remains on track with yesterday's analysis.
The models have come into closer agreement on timing and track, bringing Isaias through the area as a tropical storm during the day and evening tuesday. For the MAPSO area, Isaias remains a mostly rain event, with forecast 2 - 6 inches, 3 - 6 if we include the potential predecessor rain event Monday night.
For today, a heat advisory remains in effect because of the high humidity. There is a 50/50 chance of thunderstorms this afternoon and evening.

The MAPSO area is under a TROPICAL STORM WARNING and a FLASH FLOOD WATCH tomorrow, Tuesday Aug 4
There is good model consensus on a track that brings Isaias through our area Tuesday.
Key points:
Rain: NWS forecasts 2 - 4 inches with more in isolated rain bands. There is also a potential PRE rain event tonight although this looks limited to about 1/2 inch if it occurs. Total 24 hour rain forecast 2 - 6 inches.
Wind: The highest winds are more likely to be east of us over Long Island, but the potential does exist here for an extended period of 20 - 40 mph winds with some 50+ gusts on Tuesday afternoon and early evening. The good news is that Isaias is expected to pass relatively quickly, meaning that the worst winds could be limited in duration to 2 - 3 hours.
Flooding: Local flash flooding, road ponding and local field and stream only. The river should be able to handle this event.
Timing: Chance of heavy rain from the PRE event overnight Monday. Rain likely by mid morning Tuesday becomes heavy Tuesday afternoon and early evening, tapering off by midnight. Winds Tuesday afternoon and early evening.

SITUATION OVERVIEW
------------------
Tropical Storm Isaias, located off the north Florida coast,
will continue to move to the north this morning, turning
north-northeast this afternoon along the southeast coast. Isaias will
continue moving northeast tonight over Eastern North Carolina. Isaias
will slowly weaken as it accelerates northeast on Tuesday, likely moving
over our area Tuesday afternoon and evening. There is still some timing and
intensity uncertainty with this storm. However, confidence continues to
increase with respect to the magnitude of local hazards and impacts.
The main threats with this system involve heavy rainfall, strong winds,
minor to moderate coastal flooding, along with high surf and dangerous rip
currents.
Locally heavy rain is expected with a widespread 2 to 4 inches,
with localized amounts up to 6 inches possible. The heaviest rain is most
likely to occur across New York City, Northeast New Jersey and the Lower Hudson
Valley early Tuesday morning through Tuesday evening, and eastern sections Tuesday
afternoon into Tuesday night. The strongest winds are likely to occur across Long
Island, coastal Connecticut, and the New York City Metro. Dangerous marine
conditions are likely across all of the coastal waters Tuesday and
Tuesday night. High surf and dangerous rip currents are expected along
the ocean beaches Monday through Wednesday.
The effects from Tropical Storm Isaias are expected to diminish
quickly from southwest to northeast across the area Tuesday night
into Wednesday morning.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across northeastern New Jersey, New York City, and the
Lower Hudson Valley.
Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and streams may rapidly overflow their banks in multiple
places. Small streams, creeks, canals, and ditches may become
dangerous rivers. Flood control systems and barriers may become
stressed.
- In hilly terrain, destructive runoff may run quickly down
valleys, and increase susceptibility to rockslides and
mudslides.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
* WIND:
Protect against dangerous wind having possible significant impacts
across Southeast New York, Northeast New Jersey, and Southern
Connecticut. Potential impacts include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes damaged, especially if unanchored. Unsecured lightweight
objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. A few bridges, causeways, and access
routes impassable.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines.
* SURGE:
Protect against locally hazardous surge having possible limited
impacts across shoreline communities. Potential impacts in
this area include:
- There is potential for widespread minor to locally moderate coastal
flooding across the Lower New York Harbor and South Shore Back Bays,
with localized minor flooding impacts elsewhere.
- Localized inundation with storm surge flooding mainly along
immediate shorelines and in low lying spots.
- Sections of near shore roads and parking lots become overspread
with surge water. Driving conditions dangerous in places where
surge water covers the road.
- Moderate beach erosion. Heavy surf also breaching dunes, mainly
in usually vulnerable locations. Strong and frequent rip
currents.
- Minor to locally moderate damage to marinas, docks, boardwalks,
and piers. A few small craft broken away from moorings.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast New York, Northeast New Jersey, and Southern
Connecticut. Potential impacts include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Make sure you are in
a safe location before the onset of strong winds or possible flooding.
Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.
Rapidly rising flood waters are deadly. If you are in a flood prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, Turn Around Don`t Drown!
Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge prone area, you could find
yourself cut off by flood waters during and after the storm. Heed
evacuation orders issued by local authorities.
If in a place that is vulnerable to high winds, such as near large
trees, a mobile home, upper floors of a high rise building, or on a
boat, consider moving to a safer shelter before the onset of strong
winds or flooding.
If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.
Closely monitor http://weather.gov, NOAA Weather radio or local news
outlets for official storm information. Be ready to adapt to possible
changes to the forecast. Ensure you have multiple ways to receive
weather warnings.

It is still early, and there is wide spread in the models, so please take any predictions made in the next 24 hours with a substantial degree of caution.
Hurricane Isaias is currently a messy cat 1 system just north of Haiti and east of Cuba. In the next 48 hours, it will most likely pass Cuba and turn north towards the east coast of Florida or the Bahamas. After that, it is likely to head up the east coast but models dIverge significantly after 48 hours.
We can expect Isaias to arrive at our latitude between Tues and Wed as a strong trop storm or a cat 1 hurricane based on the current model runs. The storm is slightly more likely to pass just offshore than on land but cannot rule out either at this time. Expect there to be some effect on the area, although what and how bad are still very much up in the air.
