The Atlantic is quiet; Pakistan monsoon rains continue; last day of Russian heat wave
Posted by: Dr. Jeff Masters, 1:54 PM GMT en Agosto 18, 2010 +3
A tropical wave in the Caribbean near Jamaica is generating disorganized thunderstorm activity over the central Caribbean. Wind shear is a moderate 10 - 20 knots over the region, and water vapor satellite images show that there is some dry air to the west of Jamaica that will interfere with any development that might occur. None of the reliable computer models develop this wave.

The GFS, NOGAPS, and ECMWF continue to predict that a tropical storm will form between Africa and the Lesser Antilles Islands 3 - 7 days from now. A strong tropical wave currently moving off the coast of Africa is a good candidate for such a development. The NOGAPS model is predicting the development of a strong tropical disturbance near the coast of Honduras this weekend.


Figure 1. Extreme flooding along the Indus River in Pakistan has swollen the river to 16 miles (24 km) wide in sections, as seen in the top image from yesterday. For comparison, and image taken a year ago at this time in August (bottom image) shows that the Indus is normally just 1 - 2 km wide during monsoon season.

Extreme flooding and monsoon rains continue in Pakistan
In flood-ravaged Pakistan, heavy monsoon rains hit the Punjab region in the northeastern portion of the country yesterday, dropping up to 113 mm (4.45") of precipitation. The main river in Pakistan, the Indus, continues to cause extreme flooding, and has expanded to 16 miles (24 km) wide in some sections (Figure 1.) Dr. Ricky Rood, who writes our Climate Change Blog, has a sister that works in Pakistan. He has a must-read analysis of the catastrophe in Pakistan, "Pakistan: A Climate Disaster Case Study".

Moscow hits 93°F on the final day of the Great Russia Heat Wave of 2010
Temperatures at Moscow's Domodedovo airport hit 34°C (93°F) today, which is 13°C (22°F) above average. However, pressures are falling rapidly and winds are picking up out ouf the southwest in advance of a powerful cold front that promises to sweep through all of European Russia tonight, finally bringing an end to the Great Russian Heat Wave of 2010. The latest forecast for Moscow predicts Thursday's high will be just 21°C (69°F)--essentially average. With tonight's cold front will come rain to help put out the fires that continue to plague Russia with toxic smoke. Cool temperatures near of below average over the coming week will also help fire-fighting efforts.

ok i will take your word on it i must be reading it wrong just know that 10 thus far is record slow for both basins in both storms and ace so if they lasted longer than all the storms in 09 just seems odd


Look at it real close. It is a 24 month running average. So that would eliminate the immediate ups and downs that occur most current.

I know that is a thick plume that came off 6 days ago, and is still entrenched. This is why the waves coming off NOW arn't showing any strong convection. When that layer lifts notth or some waves start to suck in most of it in, then it's on! What will happen if another dust plume comes off and is just as big? No development of the waves coming of Africa thats what. . all im saying...It was suppose to be Hyperactive this year...slow start or we need to look at what is hindering these waves from developing this year. TUTT, SAL and I guess the stability in the atmostsphere. The MJO is forecast to enter the Atlantic in about 2 to 5 days. Don't really think you can truthfully forcastthe MJO to be honest. It's too unpredictable. This season has been a head scratcher. But Hurricanes will always be the storm that no one can predict and even be right about half of the time. We still can't pinpoint when or why stuff we dont see either disapates a storm or intensifys it to a Cat 3 or more in 36 hours. That stuff is always stastatics shown after a disaster happens. No one knew there was an Eddy with very warm water and high TCHP in the Gulf until Katrina rapidly intensified from Cat 1 to Cat 5.

Well I hope PGI31L isn't thinking of consolidating at 10N, that would alter its path.
