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.

I have been given HUGE leeway in speech here. There is no suppression of speech here. This is the only time this has happened to one of my many comments. Focus should stay on tropical weather and climate. But larger discussions had during slow times can be enlightening and allow for a good back and forth of ideas. When I go too far, which has happened twice, WU says "See ya in 24". WU does a great job in allowing free speech in my opinion.

What would happen to the blog if this were to happen for the rest of the season? hmmmmmm. Talk amongst yourselves.

The 1930 Atlantic hurricane season was one of the least active hurricane seasons on record, with only three documented tropical cyclones. In the North Atlantic Ocean, hurricanes generally form between the months of June and November, with most occurring in August and September. The first system of the year formed on June 14 and the last dissipated on October 21. Two of the three storms developed into major hurricanes and the latter of these was one of the deadliest tropical cyclones on record, killing between 2,000 to 8,000 people in the Dominican Republic.
I'm sure their were at least a few other storms..Maybe nine named storms for the whole season.

Guys, most of you I can depend on for weather, and I would like to know, when these storms should get to us, because I want to go to the pool and the next session is from 3-5 and if a thunderstorm happens we can't swim anymore. So when will these storms catch up here?

I am in Pasadena MD.
And if we get kicked out because of a tstrm there is no refund.

I don't think I've ever seen someone's post disappear just because they had an unpopular belief. I think some of Nea's posts way back may have been removed by trolls because he's so outspoken on AGW, but I hardly believe people minus-ed whatever you said that quickly, Tribucanes. Sometimes, the blog just eats posts. I've had that happen to me before.

This freedom of speech spill is just too funny...

All the Cumulus seem to be bending over the last couple of days here in Mid TN... Is this normal.. Hydrus??

there is probably shear within the layers the cumulus are penetrating. It does appear a fair bit of twisting is occurring in the lower to mid levels. However, at this time the winds are pretty weak throughout in TN.

I wonder if previous years had water pooling on the ice so early in the season. With about 2 more months of melting to go, it's not hard to imagine ice-free spots near the north pole in early September.

I do not understand what you mean by bending over. As for the weather over Mid TN, we are entering a wet period late week. Might even have some severe . The upper low over Georgia has a cold pool associated with it, and will enhance the normal summertime thunderstorms over our area. They will be slow movers and could cause some flooding.

4-5 days ago it was a few small puddles on the left & maybe one on the right.

I assume the poles are only set in ice. I don't remember than leaning so bad, could be wrong. Been posting livecam all week but haven't captured any images to compare.

Maybe chaos is just chaos too. And parts of it accidentally take on an orderly appearance, and because we are a part of the latter, we seek a likeness to ourselves, just like most men seek a mommy figure to couple with.
i would use your argument to support mine, such that our innate sensibilities require a specific bandwidth of order rendering non-recognizable patterns as 'chaotic'. i suggest that the universal fabric is a pattern, whether recognizable by our senses or not. big fan of fractal cognition here ;)

I've noticed that the ocean temperatures off the middle atlantic & northeast coast up to nantucket have been a good deal above average. The 80 degree isotherm goes all the way up to NJ and then just offshore of NY/ Nantucket. I guess in theory this means that if a hurricane took a path up the East Coast that it conceivably could continue to strengthen all the way up to latitude 39 or so, non taking in other factors such as wind shear/ etc.

Usually hurricanes start their decay at or about the latitude of Cape Hatteras when they hug the coast.

Discuss.
