yes Ollie,
over the northern antilles rainfalls are quiet hefty.
the weather we have actually near/over us is a weak Tropical Wave, it does not even have a Invest Number from NOAA and I do not give it any chance to develop into any Storm, but it is a Tropical Wave with a Rainload and some strong Winds in some small Portions.
it's mainforce and very most of the Rainload is located south of PR, South of the Mona Passage and South of the DR's Southshores, tracking mostly and slowly Westward, so the most possible outlook by my opinion is an other couple days of many clouds and some short isolated Rains on the East and NE and North, more Rains and maybe even some stronger winds for the SE and Southcentral, for the SW of the Country I would expect heavy rains and strong winds, I guess the Bomberros in the Capital City are on Alert since this afternoon at least for a 'maybe' waterload.
as for Invest 99L, right in the middle of the Highway/between Africa and the Lesser Antilles,
that one starts to get interesting and a object to be watched.
it is very close to the 10th"N and the same Time way South of bothering Dry saharn Air.
the Forecast on it's western track for the next days(keep in mind that we are talking here about the Longrange Forecast of maybe upcoming/changing Conditions of a 1000 miles long Track of conditions which still do not exist at this moment, so there are possibilities to change such conditions at any moment from now on) stays very favorable for a Storm to develop with hot Sea Surface Temps, very low Windshear and Dry Air out of bothering Range.
but by my own observation of the Tracking and the "predicted" conditions I see only a very tiny Path on which a Tropical Depression by late Thursday/early Friday and then a Tropical Storm by Sat/Sund could Form and then intensify in a dangerous Speed, and that Tiny Path is the following:
to get enough Spin to start a Storm in the first place, with the needed Surface Circulation, it has to pass North of the 10th"N, around the 12th"N a Storm would actually be in Stormies Paradise for a quick grow up by actual conditions,
but the Path is named by myself very TINY because coming close to or reaching the 15th" the Influence of the Dry saharn Air would start to suck da Bugger and the same Time/Location the actually very low windshear would increase by several Times in a medium-high range Level, both together would hinder a quick intensification, maybe would hinder a build up of a Storm completely.
independend of development with til now zero Surface Circulation, the System already shows that it spins a Very Large Area up in the Atmosphere, means it collects Moisture over a very wide Area, so independend of development it will carry/move a lot of moisture towards the islands and heavy Rains can be expected for the Antilles starting next weekend/early next week.
during the next days we need to watch the position/Track to see if it moves more NW wards where it would stay weak or would not even develop, or if it runs between 10th-14th"N and may get a chance to become a significant Boy.
the actual weak Tropical Wave south of Us and the approach of 99L counted together do promise that we will most likely not encounter much humidity nor overly hefty sunburns here in Punta Cana for most of the next 10 days, but there should be a "Pause" after the weak wave left before the influence of 99L sets in to push us back to the cloudies again.
