HAZARDS AFFECTING LAND

———————-

WIND: Tropical storm conditions are possible across portions of the

northern Leeward Islands by Friday night, where a Tropical Storm

Watch is in effect.

 

RAINFALL: Fiona is expected to produce total rainfall accumulations

of 3 to 6 inches with isolated higher amounts across the northern

Leeward Islands, the British and U.S. Virgin Islands, Puerto Rico

and eastern Hispaniola.  These rains may produce flash and urban

flooding, along with isolated mudslides in areas of higher terrain.

 

SURF:  Swells generated by Fiona are expected to begin affecting the

northern Leeward Islands by early Friday. These swells could cause

life-threatening surf and rip current conditions. Please consult

products from your local weather office.
