Gulf states keeping eye on further developments

two_atl_5d0HOLT, Fla., Sept. 11, 2018–Two areas of interest to the Gulf Coast are developing while Hurricane Florence churns toward an east coast landfall.

Tropical Storm Isaac, located in the far eastern Caribbean Sea is moving toward the west near 16 mph and this general motion is expected to continue through the weekend.

IsaacIsaac’s center is forecast to move across the central Lesser Antilles and into the eastern Caribbean Sea Thursday and move into the central Caribbean Sea by Friday or Saturday.

Maximum sustained winds have decreased to near 65 mph and gradual weakening is forecast during the next few days.

Even though hurricane models show Isaac restrengthens by days four and five, there may not be much left of the storm for any strengthening to occur, according to the National Hurricane Center.

Models show Isaac weakening to a remnant low or opening up into a trough toward the end of the forecast period.

Upper-levels winds are forecast to become more favorable for development and a tropical depression is likely to form by Thursday night while the disturbance moves across the western Gulf of Mexico.

If necessary, an Air Force reconnaissance plane will investigate the system tomorrow.

Formation chance through the five-day forecast period is at 70 percent.

And out in the Atlantic Ocean, a non-tropical area of low pressure is forecast to form several hundred miles west-southwest of the Azores within the next day or so, according to the NHC.

Environmental conditions are favorable for some development and a tropical or subtropical depression could form by the end of the week while the low meanders over the northeastern Atlantic Ocean.

There’s a 50-50 chance this low pressure could develop further.
