TS Don churns west, will dissipate in Caribbean

19 July 2017

Rains from tropical storm Don were beginning to spread over the Windward Islands, the National Hurricane Center (NHC) said in its latest advisory on Tuesday.

An Air Force Reserve crew found the storm small and well-defined, but not particularly well-organized.

Forecasters say the storm is about 485 miles east-southeast of Barbados and 595 miles east of Trinidad as of Monday. Tropical Storm watches are in effect for Barbados, St. Lucia and Bonaire.

In an 11 a.m. update, the Barbados Meteorological Services said sustained winds of 39 to 73 mph (63 to 118 km/h) were expected within six hours.

Even in its weakened state, Don is expected to dump heavy rain on the Windward Islands when it crosses later tonight, increasing the risk of risky mudslides. The system is tracking west and is forecast to move across the Windward Island later today as a moderate strength tropical storm, and then enter the southeastern Caribbean Sea tomorrow, Wednesday July 19.

The National Weather Service defines a hurricane as "an intense tropical weather system with well-defined circulation and sustained winds of 74 miles per hour (64 knots) or higher".

The paper, more than 200 pages long, has been hailed as "the beginning of a new era" in mathematics and "a titanic work". Maryam Mirzakhani , the first woman to receive the Fields Medal for mathematics, has died, according to the BBC.

Met officials continue to monitor the progress of Tropical Storm Don.

In other words, Hilary might soon be opposite Tropical Storm Don.

The hurricane center said in it 10 a.m. discussion that reconnaissance flights found Don's circulation was elongated and may not even be closed on one side.

Forecasters are also keeping an eye on a second tropical wave several hundred miles west of the Cabo Verde Islands off the African coast. Don will weaken as it nears Curacao Wednesday afternoon, and is projected to dissipate shortly after passing by the northern tip of Columbia.

On the forecast track the center of Don will move through the Windward Islands late Tuesday and Tuesday night.
