Two seperate areas N of PR and NE of PR

Did these blobs just pop out of nowhere. They weren't there yesturday.Emily is just south of the blob NE of Puert Rico and moving west as the blob is not mving very much. I would think with such a strong high everything including the 2 blobs would be moving west in dandem.

I'm BUMPING this in hopes that someone will answer you. I'm trying to figure out how all of this wirks with highs and lows

In another post someone said that the blobs you are referring to are associated with an upper level low. This is forecasted to get out of the way and emily should move into the region in the next few days. Don't know if that is the case but that is similar to what I read earlier.

The more northwesterly of the two convections is associated with the upper and mid-level trough which appears to have reached its southernmost extention at this point and should begin lifting out.

The other little blob appears to be associated with some remnant of a northern extention of the wave which begat Emily. Not dead sure about that, though.

In any case, ther'll be no development from either of these areas.

If the "blob" to the north keeps going it won't be long till it looks better than Emily. It will probably fizzle though.

Ok this is probably going to sound stupid but I have to ask, I thought this was where the high pressure ridge was and that was why Emily was moving due west?

At low levels, the ridge extends into the Gulf now. At mid levels, it's thinner south of that trough but still extending over the top of Emily.

The trough will be lifting out soon, and the ridge will build in stronger all the way across the Gulf.

Thank You for explaining how it works.

That area to the NE of PR is associated with the tropical wave the moved off of Africa before Emily. THe other area is just some unsettled weather associated with that trough and I think there might be a weak swirl associated with it. Who knows what may or may not happen when the wave reaches that area of unsettled weather.

I believe that area needs to be watched because 1. the tropical wave will continue moving WNW towards Florida. 2. THe upper level winds are suppose to become favorable for development in the days ahead. 3. The water temps are plenty warm AND 4. That is about the same area Erin was spawned in '95.
Development in that area should be slow to occur if at all.

It looks to me like the "blob" has been getting bigger all day. Is this supposed to head towards Florida because it appears to be heading slightly south.
