WIND: Tropical storm conditions, mainly in gusts, are expected in
the warning area and are possible in the watch area this morning.

RAINFALL: Through today, 4 to 6 inches of rain are expected across
the island of Barbuda. Elsewhere across the Leeward and Virgin
Islands, 2 to 4 inches of rain are expected. This rainfall brings a
risk of flash flooding, especially in urban areas and in steep
terrain. For portions of Puerto Rico, moisture associated with Jerry
combined with local orographic effects may result in up to 2 to 4
inches of rain, with isolated amounts of 6 inches possible.

associated with Jerry, please see the National Weather Service storm
total rainfall graphic, available at

SURF: Swells generated by Jerry are affecting the Leeward Islands,
Windward Islands, the Virgin Islands, and Puerto Rico, and are
likely to cause life-threatening surf and rip current conditions.
These swells are expected to spread toward the rest of the Greater
Antilles today and tonight. Please consult products from your local
weather office for more information.

Puerto Rico and the U.S. Virgin Islands, can be found at: hurricanes.gov/graphics_at5.shtml?ripCurrents
