Russia records its hottest temperature in history; 97L forms near Puerto Rico
A heat wave of unprecedented intensity has brought the world's largest country its hottest temperature in history. On July 11, the ongoing Russian heat wave sent the mercury to 44.0°C (111.2°F) in Yashkul, Kalmykia Republic, in the European portion of Russia near the Kazakhstan border. The previous hottest temperature in Russia (not including the former Soviet republics) was the 43.8°C (110.8°F) reading measured at Alexander Gaj, Kalmykia Republic, on August 6, 1940. The remarkable heat in Russia this year has not been limited just to the European portion of the country--the Asian portion of Russia also recorded its hottest temperature in history this year, a 42.3°C (108.1°F) reading at Belogorsk, near the Amur River border with China. The previous record for the Asian portion of Russia was 41.7°C (107.1°F) at nearby Aksha on July 21, 2004.

Moscow on track for its hottest July in history
According to the Russian weather service, the first fourteen days of July in Moscow averaged 6.2°C above average. The record hottest July, in 1938, had temperatures averaging 5.3°C above average, so Moscow is on track to set the record for its warmest July in history. The past four days, Moscow has averaged 8.2°C above average. The heat wave peaked on July 17, when the mercury hit 35.0°C (95°F). Moscow's hottest temperature of all-time is 36.6°C (98.2°F), set in August, 1920. With the wunderground.com forecast for Moscow calling for high temperatures between 31 - 38°C (88 - 100°F) for the coming week, no end to the heat wave is in sight. Weather records for Moscow extend back to 1879.
Russia's remarkable heat wave has led to a state of emergency to be declared for 19 of Russia's 83 provinces, and record number of Russians have been drowning in swimming accidents as they take to the water to escape the heat. Over 1200 Russians drowned in June, with another 233 dying between July 5 and 12. The heat has also created dangerous levels of air pollution in Moscow, and severely impacted agriculture.
Nine new national extreme heat records this year
As I commented in Friday's post, six nations in Asia and Africa set new all-time hottest temperature marks in June. Two nations, Myanmar and Pakistan, set all-time hottest temperature marks in May, including Asia's hottest temperature ever, the astonishing 53.5°C (128.3°F) mark set on May 26 in Pakistan. Last week's record in Russia makes nine countries this year that have recorded their hottest temperature in history, making 2010 the year with the most national extreme heat records. My source for previous all-time records is the book Extreme Weather by Chris Burt. I thank Mr. Burt and weather records researchers Maximiliano Herrera and Howard Rainford for their assistance identifying this year's new extreme temperature records.

Two tropical waves worth watching
A tropical wave passing over the Virgin Islands this morning will bring heavy rain and possible flooding to Puerto Rico today. This wave was designated Invest 97L by NHC this morning. The wave is under about 20 knots of wind shear, due to strong upper-level westerly winds. The strong upper-level winds are associated with the counter-clockwise flow of air around an upper-level cold-cored low pressure system a few hundred miles north of Puerto Rico. Satellite images of 97L show a moderate area of disorganized thunderstorms to the north of Puerto Rico, but no signs of a surface circulation, low-level spiral banding, or upper-level outflow. There is a large amount of dry air to the north of Puerto Rico that will interfere with development of 97L. As the wave progresses west to west-northwest through Wednesday, thunderstorm activity will increase, due to interaction with the upper low. The rains from these thunderstorms will bring the threat of flooding to the Dominican Republic on Tuesday and Haiti on Wednesday. The upper low will also bring high wind shear of 20 - 30 knots over the the wave through Wednesday. No development of the wave is likely until at least Wednesday, when the SHIPS model predicts shear will fall to the moderate range, 10 - 20 knots. At that time, 97L will be over the eastern Bahamas and eastern Cuba. However, none of the reliable computer models is calling for tropical cyclone development over the next seven days. I expect 97L will enter the Gulf of Mexico early next week. NHC is giving 97L a 20% chance of developing into a tropical depression by Wednesday. The Hurricane Hunters are on call to fly into 97L Tuesday afternoon, if necessary.
A second region of concern is a tropical wave in the Western Caribbean, near Jamaica. This wave is currently producing widely scattered thunderstorms, and shows no signs of organization. However, wind shear is a light 5 - 10 knots over the wave, and we need to keep an eye on this one. The wave will continue to the west at 10 - 15 mph this week, and will bring the threat of heavy rain to Belize and Mexico's Yucatan Peninsula late this week. NHC is giving this wave a 20% chance of developing into a tropical depression by Wednesday.

Wind and ocean current forecast for the BP oil disaster
East to southeast winds of 10 - 20 knots will blow in the northern Gulf of Mexico today through Friday, according to the latest marine forecast from NOAA. The resulting ocean currents should push the oil to the west and northwest onto the portions of the Louisiana nearest the Deepwater Horizon blowout location, according to the latest trajectory forecasts from NOAA and the State of Louisiana. The long range outlook is uncertain, and will depend upon what 97L does. It's a pleasant relief to look at the trajectory maps and not see the usual bull's eye of high oil concentrations at the blowout site! However, there is still plenty of oil in the Gulf that will slosh onto shore in the coming weeks and months.

Ha! Good luck!
I love that hotel, gone several times myself, local tourism. :D
NWS Link
so can we say weak axis strong axis depending on the strength and angle of the wind change?
Well defined axis?
Western Canada. Even with parts of Siberia getting fried the weather is Alberta is cool and wet and has been like that for most of this summer so far.
So if you want to escape the heat try Alberta or British Columbia. It's about the only place you will find that is not basking under a hot sun
lol, i have no idea
My understanding is that it's pretty much unlimited...

I wonder what the record is anyway......I only have a couple.
eyes can only form on strong TS or hurricanes; so no there is no eye forming

I'm at 81 right now and I've been over one hundred
Gas bubbles around base of original BOP. I doubt that is a good thing. Several "anomalies" from 80 to 200 meters out from wellhead.
I love folks that appreciate sarcasm.
LOl no, but it seems to be rotating somewhat which might be a satellite illusion since vorticity wise there's nothing, its probably waning a little in convection due to D-min.

81! yikes!
Apparently I'm a very tolerant person with just under 10 XD
Yeah, that .80 reading was dated and from the NE tip of the island...
I ignored handles he didn't make yet when he was in the Miami television stage. Worked quite well.
It's like they have their phones set to receive texts anytime the word Invest shows up on the website. Really getting out of hand, without a doubt by the time the 8:00 rolls around the trolls will have this thing skirting the entire coastline as a CAT5. Stop the nonsense, it has a long way to go "if it makes it".
i think its un-endless
just like teh un-endless names
No, you're not...LOL
Most of the ones from the last month or so have been a certain someone who keeps circumventing the ban...with a few notable exceptions
I've become more tolerant and every season I pardon some of the least obnoxious violators...there are some on my list that I ignored the day the option became available and they've stayed there
