FLORIDA, United States, Tuesday November 13, 2018 – A tropical wave that forecasters had suggested could later this week become Tropical Storm Patty has lost steam and is not expected to develop further.
The wave, interacting with an upper-level low, continues to cause disorganized showers and a few thunderstorms from the Leeward Islands to Puerto Rico.
But the National Hurricane Centre (NHC) in Miami now says “significant development of this system is not expected due to unfavourable upper-level winds and interaction with the islands of the Greater Antilles”.
There is a low – 10 per cent – chance of further development in the next 48 hours and 20 per cent chance of development over five days.
Regardless of development, however, the system is forecast to bring locally heavy rainfall to portions of the Leeward Islands, the Virgin Islands, and Puerto Rico over the next couple of days as it moves generally westward to west-northwestward.
Up to yesterday morning, forecasters described the tropical wave as “vigorous”, saying it might have become the 16th named storm of the 2018 Atlantic hurricane season, just over two weeks before it ends.
The season officially runs from June 1 to November 30.
