The National Hurricane Center is tracking three disturbances early in this Atlantic hurricane season, one of which rates a mention in discussion among National Weather Service forecasters in Tampa.
The disturbance known as Invest92L in Mexico’s Bay of Campeche will move north toward the western Gulf of Mexico by the weekend but presents no immediate concerns for the Tampa Bay area, the Weather Service said in a forecast discussion Monday.
The other two disturbances appeared unlikely to pose any threat to the United States.
One developed into a tropical depression Monday morning, about 90 miles southeast of Cape Hatteras, N.C. The Hurricane Center said it’s expected to move northeastward away from the U.S. As of Monday evening, the storm slowed slightly with maximum sustained winds of 35 mph. Tropical storms form when winds speeds reach a minimum of 39 mph. It will likely become Tropical Storm Bill in the next day.
The other system is a strong tropical wave just offshore of west Africa that’s expected to see some development in the next few days before a combination of dry air and strong upper-level winds limit any chance it becomes a tropical cyclone, the Hurricane Center said.
The disturbance off Mexico might affect other weather systems in Florida, the Weather Service said. It has a 70 percent change of developing into a tropical depression late this week as it moves across the Gulf. Heavy rains could impact portions of the northern Gulf Coast by Friday.
The Atlantic hurricane season runs from June 1 through Nov. 30, but tropical storms have been forming early in recent years. Storms posing the greatest threat to Florida generally form later in the season.
Meantime, the rain chance in the Tampa Bay area is 50 percent to 60 percent through Thursday, the Weather Service said. Highs were expected to be in the upper 80s and lows in the upper 70s.
