*** There will be no impacts from tropical systems for the U.S. through the weekend ***

An area of low pressure continues over the Central Atlantic well to the east & southeast of Bermuda. The low will soon hook up with a cold front so no true tropical development is expected.

Another nontropical low is over the NE Atlantic & will slowly move move south/southwest with some subtropical development possible while the system is over the Eastern Atlantic & west of Portugal & southeast of the Azores.

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.
