Isaias has formed. Surface eye located by Hurricane Hunters.

While this system continues to organize & I expect to see it upgraded to Tropical Storm Isaias later today or tonight, it’s forecast is highly uncertain & we are in wait and see mode right now. What I will say is that the stronger it becomes over the next 36 hours will dictate how it will be impacted by shear and possibly dry air near Florida. If it is disrupted heavily by land interaction with Hispaniola and even Cuba, then at the very most, a very weak tropical storm impact would be possible for Florida this weekend. On the other hand, if it ends up not being disrupted by land interaction, it may have a “fighting chance” to battle the shear and dry air & be more of a moderate to upper end tropical storm. All-in-all, this system has an uphill battle in front of it.

1. Isaias will produce heavy rains and potentially life-threatening flash flooding and mudslides across the Virgin Islands, Puerto Rico, the Dominican Republic, northern Haiti, and over the Bahamas.

2. Tropical storm conditions are likely across portions of the the Virgin Islands, and Puerto Rico through this morning and will spread westward to portions of the Dominican Republic, Haiti, and the Turks and Caicos and the Bahamas later today and Friday. Tropical Storm Warnings are in effect for these areas. Do not focus on the details of the track forecast, as rainfall and wind hazards will extend far from the center of the system.

3. While this system could bring some rainfall and wind impacts to portions of Cuba and Florida later this week and this weekend, it is too soon to determine the location or magnitude of those impacts. Interests there should monitor the progress of this system and updates to the forecast over the next couple of days.

Looks as if we are presently in an upper cloud level gyro or what ever they are now calling them, basically a large area of anticlockwise air motion, which typically has many ITCZ swellups associated with it. . . It started yesterday as I indicated, with rain in a number of places, but not much in Belize, now there are many swellups all over Belize, many with rain, some rain will be very heavy. The large cloud area in the Atlantic has started to rotate and they have now called it TS ISAIAS but they expect it to go over Haiti and north of Cuba and east of Florida, so no effect for us. But there is more cloud developing just off Africa, which we must watch.

Looks as if virtually all Belize will be under heavy cloud much of the day, with many individual swellups, and many places of rain, some heavy, for all the morning.

On Ambergris Caye this morning we have rain and an overcast sky. The almost official island udometer reads only an inch but it seems like much more. It might need calibrating. The wind is from the East at 10 mph and the sea state around our Barrier Reef is moderate. Today's expected high temperature is 86 f.

Present Condition: Wind and rain. Moist and unstable conditions have been supporting thunderstorm activity across the country today... A gradual decrease in moisture is expected during the next 12 hours or so...
24hr Forecast: Continuing mostly cloudy with a few showers and isolated thunderstorms this afternoon. For tonight and tomorrow morning, showers and thunderstorms will be isolated, except for a few more occurring mainly over the south. Small craft caution in effect for gusty winds and locally rough seas near heavy showers and thunderstorms. There is the possibility of localized flooding, especially near rivers and streams in the south.

I have no idea how tomorrow, Friday will work out.. . Presently, there is all sorts of stuff around us. . . We could be clear of most of it, or in the thick of it tomorrow.
