At 10:30 pm, It's cleared up some in Romana, winds are down to about 10-15 mph, still a cold breeze though. Still a Little rain here and there. In looking at the satellite pictures, it looks like there's a lot more coming our way though.
Latest report from hwn.org says: A TROPICAL WAVE OVER THE EASTERN CARIBBEAN IS PRODUCING CLOUDINESS AND SHOWERS OVER HISPANIOLA...PUERTO RICO...AND THE LEEWARD
ISLANDS. UPPER-LEVEL WINDS ARE CURRENTLY UNFAVORABLE FOR
TROPICAL CYCLONE FORMATION... BUT COULD BECOME SLIGHTLY MORE
FAVORABLE DURING THE NEXT DAY OR TWO AS THIS SYSTEM MOVES WESTWARD AT 15 TO 20 MPH.
guess maybe things could become slighly more favorable for formation in the next day or so since their last notice 5 hours ago...let's see...!

Thanks Lynn, just to note, this wave will most probably have moved away from us by the time it could develop. We will see a few more tropical storms/thunderstorms and wind.

There is nothing else at the moment showing signs of tropical storm development, although the weather overall is quite active, right from the African Coast, through to us here in the Caribbean.

Forecaster Beven tells us that the cloudiness and thunderstorms that we are experiencing is as a result of the tropical wave that we discussed yesterday. This wave has become a little more concentrated now in the area of the Southeastern Bahamas, a little NorthEast of us. Should this system develop, it should be past us already.

Elsewhere...tropical storm formation is not expected for the next 24 hours.

It sure is wet out there!

The National Hurricane Center has just released this statement.....

A ship in the vicinity of the strong tropical wave located just east of the Central Bahamas has recently estimated winds to tropical storm force. Satellite imagery and radar data from the Bahamas indicate this system has continued to become better organized today. An air force reserve unit reconnaissance aircraft is currently enroute to determine if a tropical depression or a tropical storm has developed.

On the positive side, and if this can be read that way, looks like the DR is due for some good weather days at least for a few days.

Another name bites the dust! The tropical wave that moved across us over the past few days decided to organize itself into tropical storm Franklin in the NorthWestern Bahamas. This should not have any effect on us here.

The tropical wave associated with the storm is now well NorthWest of us and we should see what I call normal weather... sunny and hot interspersed with tropical showers to keep us a little cool.

There are two tropical waves over the hurricane birthing grounds in the Atlantic as well as a weaker wave a little to the South of us. We are not expecting any of these systems to develop.

It seems that after a very active start to our storm season, we're getting a well deserved small break right here on our Island. This is what we look like right now.. http://www.goes.noaa.gov/browsh.html

Mostly clear skies above us...

http://www.goes.noaa.gov/browsh.html

An East Atlantic tropical wave is moving into the Lesser Antilles with dry atmosphere up ahead of it and moisture on the back of it. Apparently the skies down South are quite hazy with the amount of Saharan dust that this wave carries with it.

Another quite extensive tropical wave in the Eastern Caribbean scattering some showers over Venezuela.

A third weak tropical wave along central Columbia and stretching into the Pacific is scattering isolated showers over Southern Panama.

Of course to the NorthWest of us is tropical storm Franklin and yet another tropical wave over the Yucutan Peninsula that is producing heavy rains in that area.

Let's enjoy our days of sun and fun. We seem to be at a point at the moment where the weather systems kinda miss us, either drifting somewhere to the East or West of us, or only forming after the waves pass us.

Another name bites the dust. To the North of us, Tropical depression 7 has changed into tropical storm Gert. We have clear skies with just some wispy cloud.

Here is a fascinating water vapor satellite image that shows us quite peaceful, while storms rage around us..

Very little cloud cover and we can look forward to a hot, hot day.

Looking over the Atlantic, two tropical waves are slowly making their way across to our side of the world and we will have to see what they develop into, if anything.

One very weak tropical wave is touching us now, but water vapor imagery shows very little deep moisture over the Caribbean at the moment, with a few showers/thunderstorms associated with the tropical wave. This wave has brought African dust into the Western Caribbean and this dust seems to be hindering the development of a deep convection. This dust can produce hazy skies as the wave continues moving west.

At the upper levels...a mid/upper level trough splits the Caribbean from a weak upper low over East Hispaniola SouthWest to the coast of Central America, right around the Nicaragua/Costa Rica border.

The Mid/upper high East of the Lesser Antilles is advecting tropical moisture over the Caribbean and producing scattered showers around the ABC Islands.

It looks like we'll continue with a few quiet days, hot with scattered showers, as the systems above us and around us are still deciding whether to develop or not.

Nothing much changed from yesterday. We still have a breathing space before we have to be on the lookout for the next system.

Enjoy the very normal Caribbean Summer Weather!
