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).
