DISCUSSION AND OUTLOOK
At 800 PM EDT (0000 UTC), the center of Tropical Depression One was
located by an Air Force Reserve reconnaissance aircraft near
latitude 28.9 North, longitude 77.9 West. The depression is moving
toward the northeast near 14 mph (22 km/h). A motion toward the
northeast or north-northeast is expected tonight into Sunday
morning. After that time, a faster northeastward motion is
expected. On the forecast track, the depression is expected to
remain well offshore the east coast of Florida and Georgia tonight
and Sunday, and then move near or east of the coast of North
Carolina on Monday.
Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Gradual strengthening is forecast, and the depression is
expected to become a tropical storm on Sunday.
The minimum central pressure recently measured by a reconnaissance
aircraft was 1006 mb (29.71 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are possible within the watch
area on Monday.
RAINFALL: The depression is expected to produce additional rain
accumulations of 1 to 2 inches over the central and northwest
Bahamas, and generally less than 1 inch over south Florida through
tonight. The depression is also expected to produce total rain
accumulations of 1 to 2 inches over coastal North Carolina Sunday
night and Monday.
SURF: Swells generated by the depression are affecting portions of
the east coast of central and northern Florida. These swells are
expected to spread northward during the next few days, and could
cause life-threatening surf and rip current conditions across much
of the U.S. southeast and mid-Atlantic coasts. Please consult
products from your local weather office.
