A weak upper trough/low pressure area is over the Bahamas drifting west around the Bermuda High. No surface development is expected but there will be an uptick in heavy showers & tstorms for Florida, the Bahamas & nearby areas through Tue.

Dr. Phil Klotzbach, CSU updated his seasonal Atlantic Basin tropical cyclone forecast Thu. & did up the #s a bit. Looks like a busy few months ahead. Always be prepared.

Saharan dust. Dry air - yellow/orange/red/pink - is extensive over the Central & Eastern Atlantic. Such widespread dust is common early in the hurricane season & is indicitive of dry air that can impede the development of tropical cyclones. However, sometimes wanna be waves will just wait until they get to the other side of the plume then try to develop.

2021 names..... Fred is the next 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 in 19 & Laura, Eta & Iota in 20). Last year - 2020 - had a record 30 named storms. The WMO decided beginning in 2021 that the Greek alphabet will be no longer used & instead there will be a supplemental list of names if the first list is exhausted (has only happened twice - 2005 & 2020).
