TS Bret and an Atlantic Blobette: July 19, Update A

TS Bret is currently at around 30.8N, 74.8W, and is moving NE at 8mph. Winds are now officially down to 50mph, making him a weak-ish sort of storm (central pressure 999mb). As you can see from the attached satellite image of Bret, there are lovely whispy clouds in the northern and eastern side of the system, with some heavier clouds (no rain) in the southwest quadrant. As I thought yesterday, the wind shear really was not enough to compensate for the other factors that were working to stop him from intensifying further. With such little convection, I don't really consider this a tropical storm anymore, but there is still some decent circulation in the lower half of the troposphere so the NHC will probably keep Bret as a TS for a little while longer.

There's another blobette farther out in the Atlantic. This one also does not have a lot of convection and is not very well formed yet. It is centered somewhere around 33N, 58W so it's east of Bermuda, and it is moving towards the east. Even if it develops it will remain in the Atlantic, well away from land.

It's a bit late in my corner of the world, so time for a nice nap now... more tomorrow.

Toodle pip!

p.s. In case you were wondering about the fate of TS Dora from yesterday's satellite pic, she is now a hurricane in the Pacific and may clip the Mexico/Baja peninsula over the weekend.
