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.

Yeah I think we are getting too much rain at once. My neighborhood rarely floods and when it does it is only ankle deep at most. By the way the forecast shows lower rain chances tomorrow and Friday, but back up again on the weekend, so that will be a break that I'm sure some folks won't mind.

.............GT did you get that Ligthning early this morning?,man it was Booming here along to coastline

New Hampshire

Strong thunderstorms barreled across New Hampshire on Tuesday evening, knocking out power to more than 24,000 homes and businesses, including nearly 1,000 in Manchester. Manchester fire crews responded to “a bunch of trees around the city” that came down, especially in the Hackett Hill area, said District Fire Chief James Michael. “Some hit wires; some didn't.” Hooksett firefighters responded to 15 Fieldstone Drive for a reported lightning strike. “It hit a tree out in the back yard and traveled into the house,” Deputy Fire Chief deputy Mike Hoisington said. An electrical outlet got scorched, and the homeowners were checking to see if any appliances were damaged, he said. Not everyone got the heavy storms. Bedford police reported wind but no rain. Londonderry police also had no rain outside their station. In Rochester, a live power line fell on the Spaulding Turnpike, closing a section of turnpike. Northbound traffic went through the toll booth and then was U-turned back through the tolls in the opposite direction safely because a different section of the southbound turnpike was shuttered, according to Rochester fire Lt. Eric Lenzi.

The turnpike was closed for just over an hour. “We were just trying to empty the highway from a dangerous situation,” a state police dispatcher said. She doesn't believe people were charged to go through the toll again. Otherwise, the dispatcher said, “they'd be calling here screaming at me.” James Brown, a meteorologist with the National Weather Service in Gray, Maine, said winds topped 60 mph in some places, including Alton. “We're looking mostly for wind damage,” he said. “We've all kinds of trees down” Blame the storms on a clash of air masses. “We've got a very warm, humid air mass in place and a colder air mass coming down from Canada,” Brown said. “The two are clashing and creating these thunderstorms.” By late last night, utilities had cut the number of outages in half to more than 11,000. Farmington, Hopkinton and Rochester each had more than 1,000 customers without power. PSNH spokesman Matthew Chagnon said the outages were spread over a wide section of the state. “From what I understand, there's a lot of wires down,” he said. “There's some poles down in some cases and those can take longer because it requires different crews to come in and set the poles.”

Once it is created in the ATCF system it is automatically generated in the Navy system. I think that HPC was testing their ability to generate and update the ATCF system (they are the NHC backup) and mistakenly generated a 90s number. They then did create an 80s number later yesterday. However 91L was recently updated this morning, but with labels identifying it as a "test".


That would make sense why we saw nothing NOAA on it last night. I thought they just had no interest as is some times the case.

Either way I suppose they needed the practice. We don't always get floaters for tests. Seen a few that were labeled test, this one is 91L. Though by the time they got it up it looked too shredded for a floater. Emilie looks way better & lost her's a day or two ago.

NAVY looks like they are tracking it for the ships out there, like they do globally. For them to miss-number something hasn't been unheard of. NOAA doesn't look like they want to jump on it officially though they did put a floater on it this morning. I wonder if it has anything to do with the gfs spinning up all those lows so far north. Maybe NOAA is testing to go through the motions of following something so far north? SST anomalies have been high for months in that area..

This Monday, July 16, 2012 NASA image provided by the University of Delaware shows a crack in northwestern Greenland's Petermann Glacier. On Monday, July 16, 2012, an iceberg twice the size of Manhattan tore off one of Greenland's largest glaciers, indicated at center. Scientists had been watching a 15-mile long crack in the floating ice shelf of the glacier for several years. On Monday NASA satellites showed it had broken completely, forming the 46 square mile iceberg. Petermann spawned an iceberg twice that size in 2010. (AP Photo/NASA, University of Delaware)

This is normal. In fact, wind shear is running below average in the tropical Atlantic. El Nino conditions probably won't be felt until September or later.

Meaning August could prove to be a pretty active month for the Atlantic.

Rita, with this now pushing critical mass for Assad, will he unleash his chemical weapon capacity on the populace? Russian handlers I'm sure are telling him he can't because it would bring immediate Western responses of overwhelming nature. But, he may now have no choice in his mind; as his regime may be in it's last week or two of survival. Will Israel wait until the election is over here to go, (if they go) or will they force Obama's hand and will we see a coalition effort on Iran before the election? Huge buildup now off the Iranian coast and lets not forget Iraq and Afghanistan border Iran and we still have military strength and capability in both. Got em' surrounded and the stakes couldn't be higher.


This is all going to be a middle east showdown regardless. Gonna get crazy over there, 2013 looks to be a dire and turmoil situation for the globe. Pure chaos is underway and a future that does not look good for anyone. But we should of known long time ago this is all coming down the pike, but as usual everybody will be questioning how we got here....just like the wild weather

“Chaos is what we've lost touch with. This is why it is given a bad name. It is feared by the dominant archetype of our world, which is Ego, which clenches because its existance is defined in terms of control.”

Perfect words. Ego has to fall in love with Chaos. I was walking through an old forest and that same thought hit me. Chaos is what works best for the world. It maximizes diversity.

True, I think it was a mistake by HPC yesterday. HPC also created Invest 82L yesterday, which had the same lat/lon at 91L.
