*** There will be no impacts from tropical systems for the U.S. through this weekend & the week of Thanksgiving ***

So... Wed. afternoon marked the first time without a named storm somewhere over the Atlantic Basin since Oct. 31 - no small feat for so late in the season.

A disturbance over the Southwestern Caribbean has been interacting with Central America so little or no tropical development is expected.

An area to watch will be the SW/West Atlantic east of the Bahamas near & along a stalled front/trough of low pressure. Low pressure will slowly develop & could become tropical or subtropical. This potential system should ultimately be steered to the northeast away from the U.S.

Atlantic Basin wave forecast for 24, 48 & 72 hours respectively:

2020 names..... “Wilfred” was the last name on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years... historic storms are retired (Florence & Michael in ’18 & Dorian is certain to be retired from the ’19 list). Interesting side note: the last six of the names on the ’20 list had never been used. So it’s on to the Greek alphabet. "Kappa” is next... the first time the Greek alphabet has been used since 2005 (total of 28 named storms using 6 Greek letter names in ’05 [there was one unnamed storm). Theta broke the record for the most Atlantic storms in a single season on record at 29.
