MIAMI, USA -- An area of disturbed weather located about 500 miles east of the Windward Islands could bring increased rainfall and winds just shy of tropical storm strength to the Eastern Caribbean on Saturday night into Sunday.
National Weather Service chief meteorologist Roberto Garcia provided an overview of the storm system designated as “Invest 93L.” The storm has not intensified and has not been upgraded to a tropical depression.
“It is not as healthy as it looked this morning and it is being impacted by severe wind shear,” Garcia said.
While the weather system has not been upgraded, there remains the potential for it to strengthen to a depression or minimal tropical storm in the next two days as it nears the Caribbean. As of now, Garcia said, the forecast calls for increased winds and rains associated with the storm system from Saturday through Sunday.
A Hurricane Hunter aircraft began investigating the low pressure system on Thursday afternoon and preliminary reports indicated that the system was producing some winds that are near tropical storm strength in the northern portion of the circulation.
Satellite images indicated that the associated showers and thundershowers diminished significantly since Thursday morning and the system presently does not meet the criteria to designate it as either a tropical depression or tropical storm. Showers and thunderstorms could redevelop late Thursday night and overnight hours, which could result in tropical cyclone formation.
Regardless of development, winds of gale force are likely to spread across portions of the Lesser Antilles beginning early Friday. Interests in the Lesser Antilles should continue to monitor the progress of this disturbance as it moves west-northwestward near 20 mph, and watches or warnings may be required for some of these islands later Thursday night or Friday.
