Tropical Storm Don forms; fourth named storm of 2017


Tropical Storm Don has formed in the Atlantic Ocean.

According to the National Hurricane Center, an area of low pressure about 500 miles east of the Lesser Antilles had developed enough to become the 2017 season’s fourth named storm on Monday evening.

Don has maximum sustained winds of 45 mph, and is moving to the west at 17 mph.

Forecasts expect the storm to continue moving westward through the Windward Islands and into the Caribbean Sea Tuesday night into Wednesday morning. Forecasters do not expect the storm to strengthen much over the next few days.

Once it enters the Caribbean, NHC forecasts predict that strong upper-level wind shear will weaken the storm from a tropical system and cause it to dissipate by the end of the week.

The NHC is also watching another wave about 1,000 miles farther east of Don as it moves in a general northwesterly pattern. Forecast odds of the wave becoming a full blown tropical system are low, about 30 percent in the next week.

2017 has yet to see a storm reach hurricane strength. Since 2011, three of the last six hurricane seasons have gone through the month of July without a hurricane forming. 2013’s Hurricane Humberto and 2002’s Gustav share the record for the latest first hurricane of the year to form since modern recordkeeping began in 1950, both forming on September 11.
