4pm FRIDAY UPDATE: Isaias (ees-ah-EE-ahs) lost a little bit of intensity in the latest advisory from the NHC, but still maintains its category-one-hurricane status. Movement is still a very speedy 15 mph to the NW.

Today, the Bahamas will feel the brunt of Isaias with gusty winds and steady heavy rain. Unlike Dorian last year that tore apart part of the islands, this will storm the islands should handle, but some flooding and storm surge impacts are possible. The storm could possibly strengthen a bit before moving over Grand Bahama tomorrow morning and approaching Florida tomorrow afternoon.

This storm will be of great interest to people living along the east coast of Florida all the way up to the mid-Atlantic states and New England. Storm surge flooding, heavy rain, strong wind and tornadoes/waterspouts are all possible for coastal Florida Saturday and Sunday as Isaias’ forward speed slows down. We expect the storm to maintain hurricane strength up until a possible landfall in the Carolinas sometime Monday. Gusty wind and heavy rain is possible from Tuesday to Wednesday up the east coast.

KEY MESSAGES

1. Heavy rains associated with Isaias may begin to affect south and east-central Florida late Friday night, and the eastern Carolinas by early next week, potentially resulting in isolated flash and urban flooding, especially in low-lying and poorly drained areas. Isolated minor river flooding is possible in the Carolinas early next week.

2. Hurricane conditions and dangerous storm surge are expected in portions of the Bahamas today and Saturday, and Hurricane Warnings are in effect. Preparations to protect life and property should be rushed to completion.

3. Tropical storm conditions are expected with hurricane conditions possible along portions of the Florida east coast beginning Saturday, and a Tropical Storm Warning and Hurricane Watch are in effect. Storm surge watches or warnings could be needed for part of this area this afternoon.

4. There is a risk of impacts from winds, heavy rainfall, and storm surge beginning late this weekend along the northeastern Florida coast and spreading northward along the remainder of the U.S. east coast through early next week. Interests along the entire U.S. east coast should monitor the progress of Isaias and updates to the forecast.
