Morocco hits 121°F (49.6°C): a national all-time heat record

The first new all-time national temperature record of 2012 belongs to Morocco, thanks to the 121.3°F (49.6°C) temperature measured at Marrakech on July 17, 2012. According to the Wunderground International Records data base maintained by our weather historian, Christopher C. Burt, the previous record was 120.4°F (49.1°C) at Agadir on July 30, 2009. A hotter temperature of 51.7°C (125.1°F) was reported from Aghadir (Agadir) Souss Massa Dra region on 17 August 1940 during a chergui wind event. However, this reading is considered unreliable by weather records researcher Maximiliano Herrera, since the temperature was 6°C higher than that measured at nearby stations.

Seven nations set all time heat records in 2011. Nineteen nations (plus the the U.K.'s Ascension Island) set all-time extreme heat records in 2010. One nation (Zambia, in 2011) set an all-time cold record during the period 2010 - 2012. With a very hot airmass in place over much of North Africa, the Middle East, and Western Asia the remainder of this week, more all-time national heat records may fall.


Figure 1. A sample image of what the new Fire Risk layer on our wundermap looks like. This is the Keetch-Byram Drought Index, one of several indices that can be used to measure fire risk. Blue and green colors represent lower risks, while yellow and orange colors show higher risk. The highest risk is shown in dark red. The legend for the Fire Risk layer explains that these highest risk areas are often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.

Wunderground releases new fire risk layer on its wundermap
Our interactive wundermap, which allows one to overlay multiple meteorological data sets, has a new layer: a Fire Risk layer. Using data from the U.S. Forest Service's Wildland Fire Assessment System, we give you option to plot up U.S. fire danger using a variety of options: Fire Danger Rating, Lower Atmosphere Stability (Haines Index), Keetch-Byram Drought Index, 10-hr Dead Fuel Moisture, 100-hr Dead Fuel Moisture, and 1000-hr Dead Fuel Moisture. According to the National Interagency Fire Center, California currently has the most number of of large fires burning of any state (5), which makes sense, given what the fire risk map above is showing.

GOM looks mighty 'lifted' to me. Aren't we in the immediate ramp-up to MJO lift phase? Or are we already there?

The Gulf is in the downward phase of the MJO and is expected to stay that way for the next two weeks or more.

It was recently reported that rain fell in Japan at a rate of 3.5 inches per hour. It was described as a waterfall. This deluge lasted for hours and threatened hundreds of thousands.

What is the world record for torrential rainfall expressed as a rate, inches per hour?

How many hours did that rain persist at that rate?

No need to worry.... happens every other day....

Explosion inside a protected area at U.S. nuke plant, says local official near Philadelphia No impact on public health says NRC

"We did get an alert that there was an unusual event over there ... there was an explosion inside a protected area of Unit 1, but it does not affect public safety," said Frank Custer, communications director for Montgomery County.

"This is not an explosion like you would normally think," said Diane Screnci, senior public affairs officer for the U.S. Nuclear Regulatory Commission in Philadelphia. "It's more like when your house trips a circuit."

Small, new, remotely-operated, unmanned aircraft are being flown in the Arctic to measure black soot. The soot is produced by burning diesel fuel, agricultural fires, forest fires, and wood-burning stoves. It is transported by winds to the Arctic, where it darkens the surface of snow and ice, enhancing melting and solar warming.

with all the people and machines we have on the north pole observing the north pole could we be causing more harm than good????

That convection (If it persist) should clean the sal for the waves that will emerge behind.


The dust will kill the convection, if there is as much dust as the satellites show.

Quoting FireWeather161:
I would welcome opinions about this.. we have managed to escape the best of the weather here in NYC so far, with heavy/severe weather off to the west, south, and northeast. Does this make us more likely to see some rapid intensification of the storms that make it here given that 1) the local area has not experienced a significant amount of turbidity (sp?); 2) The heat remains and 3) the on-shore flow from the Atlantic.

would welcome opinions about what we may experience the rest of the afternoon. (Most importantly, I need to know if I should have another cup of coffee here at work)

Stay there. Order in. Enjoy.
