HAZARDS AFFECTING LAND

Maximum amounts up to 8 inches are possible along eastern portions and the southern slopes of Puerto Rico, as well as over Haiti, the Dominican Republic and eastern Cuba. This heavy rainfall could lead to flash and urban flooding, as well as an increased potential for mudslides with minor river flooding in Puerto Rico.

1 to 3 inches of rain with isolated maximum totals of 5 inches is expected over the northern Leeward Islands, the Turks and Caicos and southeast Bahamas.

WIND: Tropical storm conditions are expected within portions of the warning area area tonight through Sunday. Tropical storm conditions are possible within portions of the watch area Sunday night.

SURF: Swells generated by Laura are affecting portions of the northern Leeward Islands. These swells are expected to spread across the northern coasts of Puerto Rico, Hispaniola and Cuba, and much of the Bahamas during the next few days. Please consult products from your local weather office.
