What happened

The episode as NWS OKX wrote it up.

The center of Isaias passed about 65 miles west of New York City at 3 pm on August 4, 2020. Tropical storm force winds extended well east of the center of circulation. The highest sustained wind speeds ranged from 35 to 55 mph, with gusts 60 to 80 mph, across Long Island, NYC and portions of the Lower Hudson Valley, resulting in widespread wind damage and power outages.

A storm surge as high as 3 to 5 ft across the Lower NY Harbor and the south shore of western Long Island, occurred during low tide, which only resulted in localized minor coastal flood benchmarks being reached in these spots. Greater impacts were realized along the ocean beachfront from 8 to 12 ft surf causing significant beach erosion and flooding. Additionally, rough surf of 4 to 6 ft on far western Long Island Sound caused damage to marinas across coastal Westchester County.

Rainfall amounts of 1/2 to 4 1/2 inches were observed across the Lower Hudson Valley, highest amounts across western areas, with 1/2 to 1 1/2 inches observed across NYC, and generally less than an inch across Long Island.

One death resulted from the high winds:|A 60 yr old man was killed in the Briarwood section of Queens near the intersection of 84th Drive and 143rd Street near Smedley Street from a tree falling on his vehicle.

One injury resulted from the high winds:|A woman was critically injured when a falling tree branch hit her while walking on Dumont Avenue in Brownsville Brooklyn.

Preliminary damage cost estimates for Public Assistance are:

|The number of power outages statewide peaked around 920000 on August 4-5th, with many outages lasting several days to a week. The state lost around xx percent of their tree population.

Area Forecast Discussion
National Weather Service New York NY
938 AM EDT Tue Aug 4 2020

.SYNOPSIS...
Tropical Storm Isaias will pass through the region today, most
likely tracking just west of New York City. A weak low pressure
trough stalls south of the area Wednesday and Thursday as weak
waves of low pressure move along it. Weak high pressure should
return on Sunday into Monday.

&&

.NEAR TERM /THROUGH TONIGHT/...
**TROPICAL STORM CONDITIONS EXPECTED TODAY**

Much of the region from NYC east this morning has remained dry
so far this morning. Expect this to continue until late morning
into early afternoon when the main feeder band begins to rotate
into the region. Adjusted PoPs to reflect this. Otherwise the
forecast remains on track, with only minor updates to
temperatures and dew points based on the latest trends.

Showers and tstms continue to develop nwd from the Mid Atlantic
this mrng, with the main axis of pcpn pivoting nwwd. This trend
will continue ahead of the approaching tropical storm. As low
lvl shear increases with the approach of the low center, the
threat for tornadoes will also increase. There has been a
history of spinups this mrng south of the area. A Tornado Watch
is in effect across the area until 4pm today.

A Flash Flood Watch continues for much of the forecast area.
The axis of the expected heaviest rainfall however has shifted
wwd, and the latest collaborated fcst indicates this. With the
tropical airmass in place however, any tstms that develop,
albeit quick movers, will have the potential to produce
torrential rain.

The highest wind threat with regard to Isaias should correspond
to the eastern semicircle of the storm. The official track
keeps almost all of the area in this sector. Current peak wind
timing is 17-03Z with the passage of the low. Sustained winds of
around 50 mph are possible along coastal areas with gusts up to
70 mph. Generally speaking however, sustained winds of 40 to 50
are more likely across the forecast area, with gusts 55 to 70
mph.

After the storm passes, sct shwrs and tstms are possible on the
backside of the sys tngt as the upr trof moves in.

A high rip current risk remains for the ocean beaches through
tonight.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
Generally fair wx is expected Wed and Wed ngt attm. A frontal
boundary is progged to remain s of Long Island, and along this
boundary will be the best chances for the development of shwrs
and tstms. The GFS was the only model to bring this pcpn far
enough n to reach the CWA, so a dry fcst has been issued. The
NBM was used for temps.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
In the wake of Isaias, a relative quiet period in store.  A closed
upper low located over Ontario combined with the subtropical
high over the Atlantic keeps the region in deep southwest flow
to begin the period. A shortwave follows by Saturday before weak
ridging builds back in for Sunday and Monday.

At the surface, a trough stalls southeast of the area, and a series
of weak surface lows will traverse this feature Thursday into
Saturday morning. This will result in increasing clouds and
precipitation chances, especially for Long Island and southeastern
CT. Surface high pressure builds in for Sunday and Monday resulting
in mainly dry conditions.

High temperatures look to be at or just above normal through Monday
as 850mb temperatures climb into the teens over the weekend and into
Monday.  The NBM with some minor adjustments was used for
temperatures and dewpoints over the period.

&&

.AVIATION /14Z TUESDAY THROUGH SATURDAY/...
***High Impact Aviation Weather Expected Today***

Isaias will quickly move across the region late this morning
into the afternoon.

MVFR and IFR conditions to start should largely become MVFR
through the morning. E-SE winds will also increase through the
morning as Isaias approaches. The greatest coverage of showers
will likely remain NW of the NYC metro terminals this morning. A
band of heavy showers and isolated thunderstorms will quickly
move across late this morning into the afternoon. An isolated
tornado cannot be ruled out this afternoon as well.
Thunderstorms have been left out of the TAF due to uncertainty
in timing and coverage.

The strongest winds are expected this afternoon with sustained
winds 30-40 kt with gusts 45-60 kt. The strongest winds will
likely occur across the coastal terminals. Low level wind shear
is likely as well as winds at 2 kft could range between 60-70 kt
17-22z.

As Isaias moves away to the northeast in the late afternoon, a
quick shift to SW winds is likely and conditions become VFR.
Winds will also gradually diminish through the evening.

.OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY...
.Wednesday...VFR with any lingering showers ending.
.Thursday-Saturday...Mainly VFR. Afternoon SHRA/TSRA possible.

&&

.MARINE...
A Tropical Storm Warning remains in effect for all waters. In
addition, a Tornado Watch is in effect through 4pm this
afternoon. Winds of 35-45 kt with gusts up to 60 kt are
expected. The wrn waters are likely to receive the strongest
winds based on the expected track of the storm. Isolated gusts
over 60 kts are possible. Conditions will then improve quickly
tonight as the tropical storm tracks into New England. Wave
heights will build to 15-20 ft on the ocean, 5-10 ft on the
Sound, and 3-6 on the bays.

Waves on the ocean will subside on Wed, but not fall blw 5 ft in
all areas until Wed ngt. A frontal system stalls south of the
ocean waters Thursday night into Friday evening with the chance
of showers and thunderstorms. High pressure returns Friday.
Winds and seas are expected to remain below SCA levels across
the forecast waters Thursday through the upcoming weekend.

&&

.HYDROLOGY...
The heaviest rainfall is expected to fall west of the Hudson
River today. Storm total rainfall of 2-3 inches is fcst across
these hardest hit areas. Elsewhere, generally an inch or less
is expected. Locally higher amounts are possible all areas
however as any stronger cells will produce torrential downpours
in the tropical environment. Confidence in any moderate river
flooding remains low due to rainfall forecast uncertainty.

A flash flood watch remains in effect through tngt for NYC,
Northeast NJ, and the Lower Hudson Valley where guidance is
lower with rain amounts for flash flood criteria. This is also
closer to the heavier rain axis forecast.

No significant widespread rainfall is expected Thursday through
Monday.

&&

.TIDES/COASTAL FLOODING...
Coastal flood warnings remain in effect for south facing
shorelines of Long Island Sound, and western Long Island, and
in/around NY Harbor, with advisories for the remaining waters.

A strong SE flow ahead of Isaias could produce surge of 2 1/2
to 3 1/2 ft in the warning area and 1 to 2 ft elsewhere. This
would result in widespread inundation of 1 to 2 ft with
localized values up to 3 ft in the warning area. Preference
continues to be toward the higher end of the PETSS and NYHOPS
guidance.

This is a one-cycle event, as winds shift W on the back side of
the storm late Tuesday evening.
