HAZARDS AFFECTING LAND

RAINFALL: Laura is expected to produce 3 to 6 inches of rain over Puerto Rico and the Virgin Islands, the Dominican Republic, the southern Haitian Peninsula and eastern Cuba through Sunday. 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 are expected over the northern Leeward Islands, the Turks and Caicos, and the southeast Bahamas.

WIND: Tropical storm conditions are expected within portions of the warning area this morning 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.
