ISAIAS is now NOT expected to regain hurricane strength approaching Florida, or any other time in its lifetime, crossing North Carolina or working off the coast of Long Island mid-week. It should be just a Tropical Storm.
While the heaviest rains and winds continue to be "away" from the Florida coast all day today (thanks to renewed wind shear), there's indications that the "steering trough" that's taking over ISAIAS will be early, and the storm will become more baroclinic with rains working around to the "left" side of the storm starting over Georgia tomorrow.
So what we used for guidance earlier, the Truman, has now been shifted slightly westward to Abercorn. The Tropical Storm WARNING includes downtown Savannah, but not the Georgia Ports or the Airport, or locations west of I-516. Hunter is right on the line.
Does rain and wind suddenly stop at this new line? Of course not. But areas that will have to deal with tropical-storm-force winds will include more of the eastside of Savannah, all coastal communities. All of Beaufort County is also in the warned area, simply due to the "low country" topography evacuating heavy rainfall and some of the heaviest rain due near high tide.
FOR BEAUFORT COUNTY RESIDENTS:
Starting tomorrow afternoon, Monday, August 3, 2020, and throughout tomorrow night, Tropical Storm Isaias is expected to bring heavy rain, potentially damaging winds and flooding to Beaufort County.
As of 2:00 p.m. today, Sunday, the National Weather Service’s National Hurricane Center is reporting Isaias to be located 370 miles south-southeast of Savannah, moving north-northwest at 9 mph with maximum sustained winds of 65 mph. Updates from the National Hurricane Center can be accessed here.
Due to the storm, Beaufort County is under a rip tide warning and strong currents have been reported at local beaches. Boaters and swimmers are urged to use extreme caution.
County residents should prepare for 2 to 4 inches of rain and tropical storm force winds between 30 and 50 mph, raising the potential for downed trees and power lines. Storm surge is expected to be between 1 and 3 feet. Low-lying areas may experience flooding.
Beaufort County Sheriff's Office Emergency Management Division is asking that all residents stay indoors during the storm and refrain from driving.
The County will remain under tropical storm warning through Monday evening, possibly longer.

DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Isaias was
located by NOAA Doppler weather radars near latitude 26.9 North,
longitude 79.6 West. Isaias is moving toward the north-northwest
near 8 mph (13 km/h) and this general motion is expected to
continue through Monday morning. A turn toward the north and
north-northeast is anticipated on Monday and Tuesday with an
increase in forward speed. On the forecast track, the center of
Isaias will move near the east coast of Florida today through late
tonight. On Monday and Tuesday, the center of Isaias will move from
offshore the coast of Georgia into the mid-Atlantic states.
Doppler radar data indicate that maximum sustained winds are near
65 mph (100 km/h) with higher gusts. Some fluctuations in strength
will be possible during the next 48 hours.
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center. During the past couple of hours, the NOAA C-MAN
station at Settlement Point, Grand Bahama Island, measured a wind
gust of 64 mph (103 km/h). A wind gust to 62 mph (100 km/h) was
reported at Freeport, Grand Bahama Island. Along the east coast of
Florida, tropical-storm-force wind gusts have been observed from
Juno Beach northward to Port St. Lucie.
The estimated minimum central pressure is 995 mb (29.39 inches).
