Latest satellite imagery show a ball of convection off the southwest coast of Florida. Invest 92L is almost off the coast or is already off the coast and this could be the beginning of some organization with this system. Some of the previous model run showed this system organizing slightly off the southwest coast then track northeast across Florida a nd strengthening to a tropical cyclone east of GA and the Carolinas. Even if it doesn't organize it would have the potential for heavy over Southern Florida during the next few days. Flood potential for the state so stay tuned to local media and the National Weather Service in Miami....RTW

EYES ON THE TROPICS 0301 PM EDT AUG 22, 2017
1. INVEST92L...Models continue to suggest weak development off the southeast coast of Florida and a track toward the northwest then northward or northeast. Some models tracks this system across Southern Florida and the Gulf then back across Florida and a track toward the northeast, and possibly strengthen into a tropical cyclone east of the eastern seaboard. We will just have to wait and see if this system does mature into a tropical entity. Showers and storms are accumulating this afternoon over the Bahamas and are tracking westward. As this system attempts to get its act together it will more than likely produce a wet environment over Southern Florida. So the next few days are looking very wet. You can't rule out localized flooding as this system tracks slowly northwest...RTW
2. INVEST 91L HARVEY continues to organize and now has a high chance for development 90% within 48 hrs. and a 100% within 5-days. Harvey is a threat for Texas and possibly Louisiana. models are all over the place but Texas seems to be Harvey's prime target for now...RTW http://ralphstropicalweather.myfreesites.net
TROPICAL UPDATE 1253 AM EDT AUG 22, 2017
000 ABNT20 KNHC 212329 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Mon Aug 21 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A large area of disturbed weather over the northwestern Caribbean Sea is associated with the remnants of Harvey. Satellite images and surface observations indicate that the system lacks a well-defined circulation and surface pressures are not falling at this time. Although this system could still become better organized while approaching the Yucatan peninsula tonight and early Tuesday, tropical cyclone formation is not expected until the disturbance moves into the Bay of Campeche on Wednesday where conditions are favorable. Regardless of development, locally heavy rainfall and gusty winds are likely to spread westward primarily across Belize and the Yucatan Peninsula during the next couple of days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. A broad trough of low pressure located near the central Bahamas and the adjacent Atlantic continues to produce disorganized showers and thunderstorms. Only slow development of this system is anticipated during the next several days while it moves west-northwestward across the Bahamas and then turns northwestward or northward near Florida and the adjacent waters. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent. $$ Forecaster Avila
