Tropical Weather Outlook
Atlantic / Caribbean / Gulf of Mexico
Area 1 (Invest 90L) - At 2:00 a.m. EDT on July 25, disorganized showers and a few thunderstorms over Hispaniola, Eastern Cuba, and the southeastern Bahamas are associated with a tropical wave. Significant development of this wave is not expected during the next couple of days as it moves generally westward near 20 mph and interacts with land. This system has a low chance (10%) of becoming a tropical cyclone during the next 48 hours. Locally heavy rainfall and gusty winds could spread westward across Cuba and the central Bahamas during the next day or so.

Remnant Low Dora (Final) - At 5:00 p.m. EDT July 24, Tropical Storm Dora, downgraded to a remnant low, was last located 150 miles west-southwest of Cabo San Lazanro, Mexico and is moving northwest at 8 mph. Dora is expected to turn north-northwest and decrease in forward speed until the system dissipates. Maximum sustained winds are have decreased to near 30 mph with higher gusts. Dora is expected to weaken to a Tropical Depression and then degenerate today. The remnant low is forecast to continue weakening and dissipating over the next few days.
