Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Aug 3 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Isaias, located just offshore of northeast Florida.

A surface trough of low pressure, located a few hundred miles north
of the northern Leeward Islands, is producing disorganized showers
and thunderstorms. Marginal environmental conditions could allow
for some slow development of this system during the next several
days, with a tropical depression possibly forming later this week.
This system is forecast to move northwestward at about 15 mph over
the southwestern Atlantic today and on Tuesday, and then stall
several hundred miles southwest of Bermuda by the middle to latter
part of the week.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...60 percent.

DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Isaias was
located by an Air Force Reserve reconnaissance aircraft and NOAA
Doppler weather radars near latitude 30.2 North, longitude 80.1
West. Isaias is moving toward the north near 13 mph (20 km/h).  A
turn toward the north and north-northeast along with an increase in
forward speed is expected later today and Tuesday.  On the forecast
track, the center of Isaias will pass well east of the Georgia coast
through this morning.  The center of Isaias will then approach the
coast of northeastern South Carolina and southern North Carolina
within the hurricane warning area later today.  The center will then
move inland over eastern North Carolina tonight, and move along the
coast of the mid-Atlantic states on Tuesday and into the
northeastern United States by Tuesday night.
 
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Some strengthening is anticipated today, and Isaias is
forecast to regain hurricane strength before it reaches the coast of
northeastern South Carolina or southern North Carolina tonight. Slow
weakening is forecast after Isaias makes landfall in the Carolinas
and moves across the U.S. mid-Atlantic region tonight and Tuesday.
 
Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center. During the past hour a wind gust to 40 mph (65
km/h) was observed at the St, Augustine Pier, Florida, and a
sustained wind of 34 mph (55 km/h) and a gust to 40 mph (65 km/h)
were measured by a Weatherflow station at the Jacksonville Beach
Pier, Florida.
 
The estimated minimum central pressure is 994 mb (29.36 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Isaias can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and
on the web at www.hurricanes.gov/text/MIATCDAT4.shtml.
 
STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
 
South Santee River SC to Cape Fear NC...3-5 ft
Edisto Beach SC to South Santee River SC...2-4 ft
Cape Fear NC to Cape Hatteras NC including Pamlico Sound, Neuse and
Pamlico Rivers...2-4 ft
Flagler/Volusia County Line FL to Edisto Beach SC...1-3 ft
North of Cape Hatteras NC to Cape May NJ including Albemarle Sound,
Chesapeake Bay, the Tidal Potomac River, and Delaware Bay...1-3 ft
 
The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large waves.
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances.
For information specific to your area, please see products issued
by your local National Weather Service forecast office.
 
WIND:  Hurricane conditions are expected within the hurricane
warning area in South and North Carolina this evening through
tonight.
 
Tropical storm conditions will spread northward within the Tropical
Storm Warning area from Florida to southern New England through
Tuesday afternoon.
 
Tropical storm conditions are possible in the Tropical Storm Watch
area in New England beginning late Tuesday.
 
RAINFALL: The following rainfall accumulations are expected
along and near the track of Isaias:
 
Northwest Bahamas: Additional 1 to 3 inches, isolated storm totals
12 inches.
 
Eastern Florida and coastal Georgia: Up to an additional 1 to 2
inches.
 
Carolinas and the mid-Atlantic: 3 to 6 inches, isolated maximum
totals 8 inches.
 
Southeast New York and much of New England: 2 to 4 inches, isolated
maximum totals 6 inches.
 
Heavy rainfall will result in flash and urban flooding, some of
which may be significant in the eastern Carolinas and the
mid-Atlantic, through midweek along and near the path of Isaias
across the East Coast of the United States. Widespread minor to
moderate river flooding is possible across portions of the Carolinas
and the mid-Atlantic. Additionally, quick-responding rivers in the
southern Appalachians and Northeast will be susceptible to minor
river flooding.
 
SURF:  Swells generated by Isaias are affecting portions of the
Bahamas and the southeast coast of the United States and will spread
northward along the U.S. east coast during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local weather
office.
 
TORNADOES:  A few tornadoes will be possible over coastal South
Carolina beginning this evening, spreading across eastern North
Carolina tonight into Tuesday morning. A couple tornadoes will be
possible on Tuesday from eastern Virginia northeastward into
southern New England.

Tropical Storm Isaias Forecast Discussion Number 25

Issued at 500 AM EDT Mon Aug 03 2020

WTNT44 KNHC 030856
TCDAT4
 
Tropical Storm Isaias Discussion Number  25
NWS National Hurricane Center Miami FL       AL092020
500 AM EDT Mon Aug 03 2020
 
Isaias continues to produce an area of vigorous convection near and
to the northeast of its low-level center.  Overnight radar data from
Melbourne and Jacksonville have shown a transient mid-level eye
feature that is located northeast of the low-level center.  The
earlier Air Force Reserve Hurricane Hunter aircraft flew near that
feature before departing the storm and found 700-mb flight-level
winds of 71 kt, with the highest SFMR winds still around 60 kt,
which is the basis for the initial wind speed for this advisory.  
An Air Force Reserve and NOAA Hurricane Hunter aircraft will be 
investigating Isaias within the next several hours.
 
The vertical wind shear that has been plaguing Isaias is forecast
to abate slightly today as the storm turns north-northeastward. All
of the intensity models shows some slight strengthening during the
next 12 hours, and the global models also indicate some deepening.
As a result, the updated NHC intensity forecast calls for Isaias to
regain hurricane status before the system moves over the coast of 
the Carolinas.  The new intensity forecast has necessitated
the issuance of a hurricane warning for a portion of the coasts of
northern South Carolina and southern North Carolina. After
landfall, Isaias is forecast to gradually weaken, but given the fast
forward motion of the storm, strong winds are expected to spread
northward along the coast of the Mid-Atlantic and Northeast United
States.  The cyclone is forecast to be absorbed by a larger
extratropical low over Canada in 3-4 days.
 
Isaias is moving northward or 355/8 kt. The track forecast
reasoning remains the same as before.  The tropical storm is
expected to accelerate north-northeastward to northeastward ahead
of a large mid-level trough over the eastern United States during 
the next couple of days. The dynamical models are in good agreement
except for some slight differences in the forward speed of Isaias.
The NHC track forecast is near the multi-model consensus aids,
which have once again trended slightly faster.
 
 
Key Messages:
 
1. There is the danger of life-threatening storm surge inundation 
along portions of the immediate coastline and adjacent waterways of 
northeastern South Carolina and southern North Carolina. 
Life-threatening storm surge is possible along the North Carolina 
coast from Cape Fear to Duck.  Residents in these areas should 
follow advice given by local emergency officials.
 
2. Isaias is forecast to regain hurricane strength before it
reaches the coast of northeastern South Carolina and southern
North Carolina, and hurricane conditions are expected in the
Hurricane Warning by this evening. Preparations should be rushed to
completion.
 
3. Tropical storm conditions are expected to spread northward 
within the Tropical Storm Warning area from Florida to portions of 
southern New England through Tuesday afternoon.  Tropical storm 
conditions are possible across other portions of New England within 
the Tropical Storm Watch area by early Wednesday.  Additional 
watches or warnings may be required later today.
 
4. Heavy rainfall will result in flash and urban flooding, some of 
which may be significant in the eastern Carolinas and the 
mid-Atlantic, through midweek along and near the path of Isaias 
across the East Coast of the United States. Widespread minor
to moderate river flooding is possible across portions of the
Carolinas and the mid-Atlantic.
