Tropical Storm “Don” has formed in the Atlantic to the east of the Lesser Antilles Islands.
A Tropical Storm Warning has been issued for the island of Grenada and Tropical Storm Watches are up for the Grenadines, St. Vincent, Barbados and St. Lucia. The storm is moving west and will bring heavy showers and gusty winds to the islands. The storm is not expected to reach hurricane status and should dissipate within 72 hours as it enters a less favorable environment. Don is the fourth named storm in what I think will be an active hurricane season in the Atlantic/Caribbean/Gulf of Mexico. Don is moving west at 17 mph. The other 3 tropical storms so far this season (Arlene, Bret and Cindy) did not reach hurricane strength (74 mph winds). Don poses no threat to the U.S.

It’s been 4,284 days (nearly 12 years) since the last major hurricane (Category 3 or higher) made landfall on the mainland U.S. – the longest period of time ever between major hurricane hits. On a global level, accumulated tropical cyclone energy is at its lowest level on record, according to Colorado State University hurricane expert Dr. Philip Klotzbach. On average, a major hurricane makes landfall in the U.S. about once every three years,” according to NOAA’s 2016 hurricane season report.
This is the Eastern Pacific, with Hurricane Fernanda (which will weaken to a Tropical Storm, then just a depression), Tropical Storm “Greg” and soon-to-be Tropical Storm “Hilary”.
