95L growing more organized; Pakistan's Indus River flood peaking downstream
A tropical wave (Invest 95L) in the far eastern Atlantic about 350 miles southwest of the Cape Verdes Islands has become more organized this morning. Satellite loops show that the wave has some rotation, and heavy thunderstorm activity has increased in recent hours, after a period overnight with little change. Water vapor satellite loops show that there is some dry air to the north of 95L, but this dry air currently appears to be too far away to significantly interfere with development. The main impediment to development is the moderate 10 - 20 knots of wind shear over the system. The shear is forecast to remain in the moderate range through Monday, then decrease. This should allow 95L to develop into a tropical depression Monday or Tuesday. NHC is giving 95L a 30% chance of developing into a tropical depression by Monday morning. With 95L's recent increase in organization, these odds should probably be 50%.

Forecast for 95L
A ridge of high pressure will force 95L to the west or west-northwest for the next five days, and the system should increase its forward speed from its current 5 - 10 mph to 15 - 20 mph by Monday. A series of two powerful troughs of low pressure are predicted to move off the U.S. East Coast next week and cross the Atlantic; these troughs should be able to pull 95L far enough to the northwest so that it will miss the Lesser Antilles Islands. If 95L stays weak or does not develop in the next five days, as predicted by the NOGAPS model, it has a chance of eventually threatening Bermuda. If 95L develops into a hurricane, as predicted by most of the computer models, it will probably recurve to the east of Bermuda and not threaten any land areas.
Elsewhere in the tropics
The ECMWF model is predicting formation of a tropical depression in the western Gulf of Mexico off the coast of Texas 6 - 7 days from now.
Pakistan's monsoon rains diminish; Indus River flood crest nears the coast
The flooding on Pakistan's largest river, the Indus, has slowly eased along the upper and middle stretches where most of the heavy monsoon rains fell in late July and early August. However, a pulse of flood waters from these heavy rains is headed southwards towards the coast, and flood heights have risen to near all-time record levels today at the Indus River gauge station nearest to the coast, Kotri (Figure 2.) The new flooding has forced the evacuation of an additional 150,000 people in Pakistan today. Flood heights at every monitoring station along the Indus have been the highest or almost the highest since records began in 1947. Fortunately, the monsoon has entered a weak to moderate phase, and heavy rain is not expected over the flood region over the next few days, according to the Pakistan Meteorological Department.

stormpetrol it look like that but I see it more like 10.8N 32.2W
This is a decent setup for gradual strengthening.
This is going to be a huge storm.
Exactly, Levi! Models don't handle ridging too well in the CATL, no matter how deep the system might be, they can create a false sense of security. Take the new GFS run, which switched from one side of Bermuda to a near miss for the east coast. Bermuda needs to be watching this very closely.
they didn't say they were uncertain for frances either and the track shifted greatly in 12 hours
LIVE STREAM ON BOTTOM OF PAGE STARTING AT 6:00 CENTRAL TIME
**Advisory graphics will be issued at 8:00 pm EDT for Tropical Depression Nine-E
Q: At maximum intensity, how strong will TD #6 be?
A. Tropical Depression
B. Tropical Storm
C. Cat. 1
D. Cat. 2
E. Higher
this is just the beginning
E. High end Category 3.
E. I think TD 6 will eventually hit Category 3 status.
exception, not the rule this time of year and it never takes much time for a ridge to flatten
and erase a temporary weakness...we will have to wait and see what happens between now and 96 hrs...still thinking northwest and then north motion for the final outcome ...
what a shock lol
I vote E.
POLL TIME!

Sorry. E, but not quickly.
You can't show the same times with 2 different runs and compare them. They will be off by at least 6 hours, possibly 12.
I suggest salt and pepper with those words and a glass of ice tea to wash them down lol
Could we please quote this every hour or something?
Thanks, Levi.
E. A cat. 4, like Bill.
cool ty
...
Alex was a borderline Category 2/3 hurricane, where have you been?
For where this will eventually go, it's anyone's guess.
