Several relatively disorganized tropical waves are over the Central & Eastern Atlantic.

One wave in particular has shown some enhanced convection at times since coming off the African coast a few days ago. The environment appears marginal which could/should keep the wave “in check” though a tropical depression or even a tropical storm might briefly develop this week over the Central Atlantic.

We also need to monitor the Western Caribbean &/or Gulf of Mexico for possible development over the next week or two as waves get farther west into a more favorable area for development.

Overall conditions over the Atlantic Basin appear “ready to go” as we head into mid to late Aug. - particularly the 20th-31st then on into Sept.

Wed., 08/05 it was Dr. Klotzbach at CSU... Thu., 08/06 it was NOAA with their hurricane season updated forecasts. Both are predicting a potentially historic last half of the hurricane season. Bottom line: always be prepared & stay calm. First Alert Hurricane Center * here *.

Saharan dust.... Tropical waves continue to “fester” along the south edge of the dust & have the potential to thrive once away from the dust.

2020 names..... “Josephine” is next on the Atlantic list (names are picked at random by the World Meteorological Organization... repeat every 6 years... historic storms are retired (Florence & Michael last year) & Dorian is certain to be retired from the ’19 list....
