Invest 91 L Becomes Tropical Depression Nine Weather System Forecasted to Remain Well South of the USVI

Invest 91 L has become Tropical Depression Nine earlier today as it continues to trek westward toward the Lesser Antilles at 17 miles per hour with maximum sustained winds of 35 miles per hour.

The National Weather Service is forecasting the weather system will remain well south of the US Virgin Islands, with no effects anticipated except for locally higher seas.

According to the National Hurricane Center, morning satellite imagery shows the low pressure system, centered at about 550 miles east of the Lesser Antilles, had become better organized overnight. Buoy data also indicated that the circulation was becoming better defined and environmental conditions appeared generally conducive for development.

A Tropical Storm Warning is in effect for Martinique, St. Lucia, Barbados, St. Vincent and the Grenadines. A Tropical Storm Watch is in effect for Dominica.

An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance this afternoon.

Two other weather systems are tailing Tropical Depression Nine.

According to the National Weather, Invest 92 L is expected pass just north of the US Virgin Islands on Sunday through Monday bringing some moderate shower activity.  The strongest winds are north side of the system, according to forecasters.

A tropical wave located over the far eastern Atlantic Ocean near the Cabo Verde Islands is producing disorganized showers and thunderstorms. According to the National Hurricane Center, gradual development of this system is possible during the next several days while it moves westward to west-northwestward at about 15 miles per hour.

VITEMA Director Mona Barnes is encouraging the community to closely monitor weather reports as the 2017 Atlantic Hurricane Season kicks into high gear.

“The 2017 hurricane season is forecasted to be a very active one and we can’t afford to be complacent,” Barnes said. “I ask that you remain vigilant and prepared as we ride out the peak of the season.”

Barnes added that now is the time to “stock up on emergency supplies, make sure everyone in your home knows what to do in an emergency, and stay informed about the weather.”
