Monsoon floods and landslides ravage China, India, and Pakistan; Colin still weak
Tropical Storm Colin continues to take its time reaching Bermuda, but should finally move past the island today as the steering currents pushing the storm northward strengthen. Colin is still suffering from wind shear and dry air being pumped in from an upper-level low pressure system to the west. Wind shear is a moderate 10 - 20 knots over Colin today, but the storm is so disorganized that it is unlikely to increase in strength more than about 10 mph before blowing past Bermuda tonight. Recent satellite imagery shows that Colin is a disorganized system, with the level-level center exposed to view and displaced to the north of the storm's heavy thunderstorm activity. The intensity and areal coverage of Colin's thunderstorms have shown a modest increase in the past few hours. Rains from these thunderstorms can be seen approaching Bermuda on Bermuda radar.
Forecast for Colin
The latest SHIPS model forecast predicts that wind shear will rise to the high range, 20 - 50 knots, tonight through Tuesday, and it is unlikely that the storm will ever attain hurricane status. Colin may bring 40 mph winds to the southeast corner of Newfoundland on Tuesday night and Wednesday.

93L
A tropical wave (Invest 93) midway between the Lesser Antilles and Africa is moving west-northwest at 10 mph. This wave has plenty of spin, but only a limited amount of heavy thunderstorm activity, thanks to dry air and wind shear of 10 - 20 knots affecting it due to a large upper-level low pressure system to the west. Wind shear is expected to stay in the moderate range, 10 - 20 knots, over the next four days, which may allow 93L to become a tropical storm. NHC is giving a 60% chance 93L will become a tropical depression by Tuesday morning. Both the GFDL and HWRF models predict 93L will develop, and the GFDL predicts the storm will become a hurricane. This storm will probably recurve out to sea, and only be a concern to shipping interests. There are no other areas of concern the models are showing for the next seven days.

The deadly 2010 monsoon kills hundreds in China and India over the weekend
The Asian Southwest Monsoon has hit yet another nation with extreme rains and deadly flooding. Northwest China's Gansu province was hard hit with torrential monsoon rains yesterday, and the resulting flooding and landslides claimed at least 127 lives. Over the past two weeks, at least 1,600 people have perished in Pakistan's monsoon floods, which some have called Pakistan's Katrina. At least 137 died in floods and landslides in the neighboring Indian state of Kashmir over the weekend, and monsoon flooding and landslides have also killed at least 65 people in Afghanistan in the past two weeks. Dave's Landslide blog has some great discussions of the flooding and destruction wrought by the terrible monsoon rains this year in Pakistan, India, Afghanistan, and China. I plan to write much more about this year's deadly monsoon later this week.
The Great Russian Heat Wave of 2010 chokes Moscow with smoke for a third day
Smoke from wildfires cause by the worst heat wave in Russia's history are choking Moscow for a third straight day today, bringing air pollution levels to three times the safe level and forcing cancellation of dozens of flights. However, air pollution is not quite as bad as it was yesterday, when carbon monoxide levels peaked at 6.5 times the safe level. Visibilities at Moscow's airport were higher today (500+ meters), but temperatures still hit 97°F (36°C). The past 26 days in a row have exceeded 30°C in Moscow, and there is no relief in sight--the latest forecast for Moscow calls for high temperatures near 100°F (37.8°C) for the majority of the coming week. As I reported in Friday's post, the number of deaths in Moscow in July 2010 was about 5,000 more than in July 2009, suggesting that the heat wave has been responsible for thousands of deaths in Moscow alone. I would expect that by the time the Great Russian Heat Wave of 2010 is over, the number of premature deaths caused by the heat wave will approach or exceed the 40,000 who died in the 2003 European Heat Wave. As seen in Figure 3, the Russian heat wave of 2010 is more intense and affects a wider region than the great 2003 European heat wave.

I'll have an update Monday.

Wow he was so not talking about you, geez overreact much?
That has already been mentioned. Possible broad surface low forming.
I think 93L is trying to close its circulation.
I think its closed, just exposed
by my name, you should know I am talking about 94L
Looks like Boca is about to miss all the red on the radar but it is getting darker.
Tks, didn't know just logged on and didn't read back.Well at least someone else noticed it.
fantastic observation jason, the overflowing pool in my backyard gave it away though
Very nice, my thinking also, the area N of Panama if it could pull more N 10-20%, but you know the tale of systems in that area this season with the exception of Alex.
While Colin poses no threat to the U.S., there are other features of interest across the Atlantic Basin that could. In fact, the potential exists for a new tropical system to form in the Gulf of Mexico and impact the Gulf Coast states this upcoming week.
The AccuWeather.com Hurricane Center reports that a frontal boundary stretched along the coast of the Southeast and across central Florida would be the culprit behind this development.
Already, an area of low pressure has formed along this front offshore of Georgia. This low is expected to move westward across the Florida peninsula tonight into Monday and emerge over the eastern Gulf Tuesday.
Once over the Gulf, this low will have an opportunity to develop into a tropical system through Wednesday. Computer models currently show this feature moving west-northwestward into an area between Louisiana and the upper Texas coast toward the latter half of the week
People with interests along the Gulf Coast from Texas to Florida should regularly check back with AccuWeather.com for updates on this potential over the next few days.
If this system does develop tropically, it will compete with another area of low pressure out over the central Atlantic for the next name on the 2010 Atlantic Hurricane Season list, which is Danielle.
For people living in and visiting Florida, the low will bring widespread, locally heavy thunderstorms to the central and southern peninsula through Monday. Flash flooding could result in some areas along with disruptions to travel.

Ok. I didn't know that until know. Thanks.
and its been wrong for most of the season
yeah, I saw that....
By your name, I would think you were talking about Oregon.
Do you have any other angles, Storm? You posted one a few days ago looking west to east
I agree 100%.
Sounds great Hydrus - I am near AquaK - but out on the barrier island and the little bit of rain we got yesterday was only a teaser...
PVbum- please call me Aqua- and I am so mad, I could SPIT. Talk about the DRY side? oh I am so mad.
*snicker*
EXCELLENT JOB!
By the way, the "dry pocket" I was in in the Tampa Bay area is definitely not dry now!
