A northeastward motion is then forecast on Friday and Saturday.

Land Hazards

Key messages for Hurricane Imelda can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.

WIND: Gusty winds on Bermuda are expected to gradually subside today.

SURF: Distant swells generated by Imelda are affecting the Bahamas, Bermuda, and much of the U.S. East Coast. Swells from Imelda will spread toward the Greater Antilles and northern Leeward Islands on Friday and continue through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
