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.

Was extremely bored so I decided to check out a ridiculously long range model and found the CFS. The first storm I saw on it was at 1044hrs, or August 27th, wouldn't that completely consume the patience of everyone here? LOL



Though, no need to worry, this is as real as Willy Wonka's factory, with oompa loompas and everything. xD


Now that would be a coincidence,as I celebrate my birthday on august 27...goodnight everyone, whoever is still on.

Dr. Masters is really turning out the new posts in the last couple of days. There was a couple days of rest, and now several in a row, all at once.

Record high minimum temperature set at Muskegon mi...

The overnight low temperature in Muskegon only fell to 79 degrees.
If this temperature stands through midnight lst... this will break
the old July 17 record high minimum temperature of 75 set in 1986.

So I know this is a tropical weather blog, but I have a weather question related to an observation regarding high temperatures for specific locations. I live in Chicago and yesterday I went to the TWC site and noticed that it stated that Chicago O'Hare's high temp for July 16th was 100, but then the official NOAA almanac (as well as the local news media)said it was 97. Today, something similar: 100 on TWC(even stating at what time in the day it occurred) while 99 is what NOAA(and everyone else) stated as the high for the same exact location (which is where official measurements are taken).

Correct me if I am wrong, but I always was under the impression that the definition of a high temperature is the maximum temperature that occurs at a given location for a given instant of time in a given day. Or does the high temperature have to stay at a given value for a certain increment of time in order for it to qualify as a valid high temperature? It would have been interesting to have had these two days be 100 degrees because that would have given the area its 6th official day this summer at 100 or better and the all-time record is 7 days back in 1988.

... Record high temperature set at Detroit mi...

a record high temperature of 102 degrees was set at Detroit today.
This breaks the old record of 101 set in 1887.

Glad to see you did some research!
Here's from the AMS on geoengineering:
"The possibility of quick and seemingly inexpensive geoengineering fixes could distract the public and policy makers from critically needed efforts to reduce greenhouse gas emissions "
This is common sense, not matter what your politics.

O'ahu's south shores invaded by mysterious creature
Reported by: Brianne Randle


The south shore of O'ahu is being invaded by something strange from sea, that even has sand crabs running for cover.

"It's the first time I've seen this, I've never seen it before," says beach goer Bruce Kuwana.

"It's really weird, it looks like you want to eat it like a little berry," says beach goer Sonya Lake.

"There are probably millions I'd say," says beach goer Scott Paddock.

If you look closely the entire shoreline is dotted with tiny, purple creatures all curled up.

"Looks like it has about it 6 legs on each side," says Lake. "Yeah it's like an avatar crab."

"When something washes up like this you don't know what to expect, maybe Tsunami stuff," says Kuwana.

It's something many have never seen before. And no one we found knew what they were.

"I definitely want to know where they came from and what they are all about," says Paddock.

Even the biologists at the Waikiki Aquarium are scratching their heads. They've been getting reports of the pea-sized crabs from Kahala to Ala Moana, all this week.

"The lifeguard called and asked what these things were because she had reports of surfers were actually have these things crawl up on their boards and onto them," says Norton Chan, Waikiki Aquarium Biologist.

He can't find a specific name for the animal - all he knows is they are some type of crab still in the larvae stage.

"What you are seeing is a swimming stage probably a few more molts before they settle into their actual crab stage itself," says Chan.

Likely the ones we spotted on the sand were dead or will be soon. He estimates there could have been millions that came up onto our beaches in the past few days.

"I don't think it's that common but ever so often when conditions are right these animals really start coming in," says Chan.

Waikiki Aquarium officials are saving some, hoping to keep them alive long enough to see how they grow.

"There's a lot of things we don't know about the ocean so any opportunity like this is a great learning experience," says Chan.

At this point it's still unknown where these crabs came from, how big they'll get and what they eat.

If you are wondering where the unusually hot and unusually cold spots are on the globe, these maps will give you an idea. These show the departure of temperature from the long-term average for the three months preceding July.

April:


May:


June:



The July map isn't out yet because, and I'm just guessing here, the month isn't over yet. But clearly the pattern of anomalies doesn't swing around willy-nilly... on monthly time scales it is a slow progression. Thus, in my expert opinion, the July map will look similar to (but different than) the June map.
