Maria is expected to rapidly gain strength and become a major hurricane as it passes through the Leeward Islands and rips through the Lesser Antilles (read British & U.S. Virgin Islands and St. Martin/St. Marteen) by Monday night (tonight)! As if they haven’t suffered enough already!
As of 0800 EDT it was reclassified from Cat-1 to Cat-2 with sustained winds of 110 mph (95 knots) and moving W-NW at 12 mph (10 knots).
EDIT: As of 1100 AST, H. Maria upgraded to a Cat-3 hurricane. By ~0800 AST it should be hitting Puerto Rico.
