FOR TROPICAL NORTH ATLANTIC OCEAN, CARIBBEAN SEA, AND GULF OF MEXICO AREA OF SPECIAL INTEREST: 10–20°N AND 40–65°W
Tropical wave 1: A Caribbean tropical wave has its axis near 64°W south of 17°N. It is moving westward from 15 to 20 kt. Scattered moderate convection is noted S of 14°N between 62°W and 65°W.
Disturbance 1 (Tropical Wave 2): Invest AL98, has its axis near 57°W or approximately 270 nautical miles east of Grenada from 04°N to 18°N, moving westward at about 20 kt. This tropical wave is producing a large area of showers and thunderstorms. Heavy rainfall and gusty winds are expected today, continuing through Monday morning, across portions of the Windward and Leeward Islands as the system moves quickly westward at 20 to 25 mph into the eastern Caribbean Sea. Additional development is forecast to be limited over the next day or two, due to the fast forward motion of the wave. The system is then expected to slow down over the central Caribbean Sea during the middle portion of the week, where environmental conditions could become more conducive for development. A tropical depression could form over the central Caribbean Sea by the middle to latter portion of this week. Formation chance through 48 hours low 10%. Formation chance through 7 days medium 60%. Given the tropical wave’s current forward speed, the axis of the wave is expected to transverse Grenada this afternoon.
The flash flood/landslide advisory remains in effect for Grenada.
The next update will be issued at 2 pm.
