Caribbean - Central America Weather

[Gustywind]

Thanks Luis and Barbara we appreciate us in the Leewards! Glad to be back to home! This afternoon i was driving near 30 km/h where usually it's 90km/h on the road! Waouw i can't believe that we have the first big active and nasty twave on June 18th!!! That means that the water temps between Africa and the 60W are enough warm to support things like 92L What does it mean for July even August without speaking about September! Just wondering...be on your guard islanders!

[Gustywind]

I will be glad to have HUC measurements (rain)...as Basse-Terre have been well showered today!

Here a heavy shower with a gust of 28 mph that I clocked with my anemometer moved thru San Juan.I think it's not over yet for Puerto Rico as I see more rain downstream.

Hola, ven algo interesante saliendo del Africa??? en los distintos mapas se puede apreciar como 2 ondas tropicales, se ven lo suficientemente bien para desarrollo o simplemente no tiene posiblidad alguna?

Hay una onda por la 37 oeste que tiene conveccion pero no se esta organizando en estos momentos.Pero hay que echarle el ojo por si acaso se organiza mas tarde.

There is a wave around 37W that has some convection,but doesn't have a well defined circulation.We have to keep an eye on it to see if later on it starts to organize.

Gusty
be careful
I have had more than my share of damaged electronics from lightning
Here in SXM skies are cloudy but we have not had much rain since this morning.
But we did have 3 inches then according to my back yard gauge.
Winds are from the E at 14 MPH
Even with a rainy morning, we were able to pull off our ZOO clean up.
It was amazing how many volunteers came out in the rain!

Here's a few of them!

so glad to hear this went off well for you today! Yeah! And love the pic.
