Humberto is centered 30 miles east-northeast of Great Abaco Island, which was devastated by Hurricane Dorian less than two weeks ago, but is a minimal tropical storm with maximum sustained winds of 40 mph. While surely a disruption to recovery efforts in the northwestern Bahamas, its bouts of wind and rain are not nearly as fierce as the onslaught inflicted by Dorian. Rainfall totals are forecast to reach 2 to 4 inches from the intermittent storms sweeping across the islands.
Squally weather is likely to continue over the northwest Bahamas, still under a tropical storm warning, for another day as Humberto gradually lifts to their north and then east.
Aside from generating rough surf and rip currents along the Florida and Southeast coast, Humberto is not anticipated to produce significant storm impacts in the United States. Florida on Friday had been under a tropical storm watch, which has since been discontinued.
The Hurricane Center forecasts Humberto to steadily intensify and become a hurricane by Monday. By the middle to latter portion of next week, the storm may come close to Bermuda, which will need to monitor its progress.
Additional disturbances under investigation
The National Hurricane Center is tracking three other areas of disturbed weather in the tropical Atlantic Ocean and Gulf of Mexico — although none have high chances to develop into storms immediately.
Gulf of Mexico disturbance
Closest to the United States, showers and thunderstorms in the eastern Gulf of Mexico could become better organized as they drift toward the western Gulf in a few days. The Hurricane Center gives this disturbance a 30 percent chance of becoming a tropical depression or storm over the next five days.
“We are watching for the potential for heavy rain during the Monday through Wednesday period next week,” tweeted Eric Berger, a meteorologist for the Houston weather blog SpaceCityWeather.com.
Eastern Atlantic disturbances
Between the west coast of Africa and the Lesser Antilles, two disturbances bear watching.
The disturbance labeled “1″ in the map above, 950 miles east of the Lesser Antilles, has little chance to develop immediately (0 percent according to the Hurricane Center) and just a 10 percent chance of developing over the next five days.
The disturbances labeled “2″ and “3″ have merged into one disturbance and have a 20 percent chance to develop into a depression or storm in the next 48 hours but a 60 percent chance over the next five days. This disturbance, about 650 miles southwest of the Cabo Verde Islands, is forecast to track westward, but its long-term track and whether it will affect land areas is uncertain.
