Hottest rain on record? Rain falls at 115°F in Needles, California

A searing heat wave rare even for the Desert Southwest sent temperatures soaring to record levels on Monday, with Needles, California tying its record high for the date of 118°F (47.8°C). The temperature might have gone higher in Needles, but a thunderstorm rolled in at 3:20 pm, and by 3:56 pm PDT, rain began falling at a temperature of 115°F (46.1°C). Most of the rain evaporated, since the humidity was only 11%, and only a trace of precipitation was recorded in the rain gauge. Nevertheless, Monday's rain at 115° in Needles sets a new world record for the hottest rain in world history. I don't think many people were outside to experience to experience the feeling of rain falling at 115°, but if they were, it must have been an uncomfortable, sauna-like experience! Thanks go to Dr. Warren Blier of the NWS Monterey office for pointing out this remarkable event to me.

It is exceedingly rare to get rain when the temperature rises above 100°F, since those kind of temperatures usually require a high pressure system with sinking air that discourages rainfall. Monday's rain in Needles was due to a flow of moisture coming from the south caused by the Southwest U.S. monsoon, a seasonal influx of moisture caused by the difference in temperature between the hot desert and the cooler ocean areas surrounding Mexico to the south. According to weather records researcher Maximiliano Herrera, the previous record for hottest rain, which I blogged about in June, was a rain shower at 109°F (43°C) observed in Mecca, Saudi Arabia on June 5, 2012 and in Marrakech, Morocco on July 10, 2010. The 11% humidity that accompanied Monday's rain shower at 115° in Needles was the lowest humidity rain has ever occurred at anywhere on Earth in recorded history, according to Mr. Herrera.

A "very rare" heat wave for Phoenix
The heat wave that brought Needles' record hot rain has broken an exceptional number of heat records in Phoenix, Arizona the past two weeks. According to the Phoenix NWS office, the "almost unbearable heat" of the first two weeks of August is a "very rare" event, and August 1 - 14, 2012 was the warmest such 2-week period in city history. The average temperature on August 6 - 13 was 100°F or higher each of the eight days, tying the record for most consecutive days with an average temperature of 100°. The temperature peaked at 116° on August 8, just 6° below Phoenix's all-time record of 122° set on June 26, 1990. The forecast for Phoenix call for a bit of relief--highs are expected to be a relatively modest 105° today, and down near 100° by Friday.


Figure 2. Morning satellite image of 93L over the Central Atlantic.

93L close to tropical depression status
A large tropical wave (Invest 93L) is located in the Central Atlantic about 700 miles east of Bermuda. Satellite loops this morning show a surface circulation has formed, and heavy thunderstorm activity has increased to the point where 93L should be considered a tropical depression, if the heavy thunderstorms can persist through this afternoon. Wind shear is light, and ocean temperatures are warm, near 28°C. The latest Saharan Air Layer Analysis from the University of Wisconsin shows that 93L has moistened its environment considerably, and dry air should no longer be a significant impediment to development. The 8 am EDT run of the SHIPS model predicts that wind shear will remain in the low range through the weekend, and I expect this system will become Tropical Storm Gordon by Friday. The storm will not affect Bermuda, but residents of the Azores Islands should keep an eye on 93L, which could pass through the islands as early as Sunday night. In their 8 am Tropical Weather Outlook, NHC gave 93L an 80% chance of becoming a tropical depression by Friday morning.

Elsewhere in the tropics
In the Gulf of Mexico, a fall-like cold front is expected to stall out early next week, and the GFS model is predicting something could start to spin up near the Texas/Mexico border on Monday. Wind shear is predicted to be low to moderate, and cold fronts stalled out over the Gulf of Mexico often serve as the seed for tropical storms.

Most of the models predict development of a new tropical wave off the coast of Africa 6 - 7 days from now.

This drought is getting pretty ridiculous now.

Salt creeping up the Mississippi River

The drought has lowered the river, letting Gulf of Mexico water enter.

"The water's perfectly safe to drink, says emergency preparedness official, however, caution urged for dialysis patients and low-sodium dieters.

The salty water has traveled nearly 90 miles into the river.

India to launch Mars orbiter in 2013

Link

(CNN) -- With New Delhi's iconic Red Fort as a backdrop, Indian Prime Minister Manmohan Singh announced Wednesday his country has set its sights on the Red Planet.

In a Wednesday speech marking India's independence day, Singh said his government has approved plans to put an unmanned probe in orbit around Mars. The mission "will be a huge step for us in the area of science and technology," he said.
It's an ambitious goal, with a planned launch in November 2013 for a 10-month flight, said Kiran Karnik, a former official with the Indian Space Research Organization.

"By the time the mission gets there, Mars will be comparatively the closest," Karnik told CNN's sister network CNN-IBN. "So there's a small window in which we need to make a launch and that's the reason the mission has to go up next year."
NASA's Mars rover set for test drive

NASA's 'Mohawk Guy' celebrates Curiosity Mars rover searching for signs of life
The goal of the mission is to search for clues to the "geology, origin, evolution and sustainability of life" on Mars, according to an ISRO report published earlier this year.

India's space program launched its first Earth satellite in 1975 and put an unmanned probe into orbit around the moon in 2008. It plans to launch its first manned spaceflight in 2016, though an Indian cosmonaut, Rakesh Sharma, flew aboard a Soviet space mission in 1984.

Mars 'Mohawk Guy' inspires Obama
The announcement comes as the U.S. space agency NASA is basking in the successful landing of its Curiosity rover August 6.

If the 2013 mission is successful, India would become the first Asian country to reach Mars: A 1998 attempt by Japan failed to insert itself into martian orbit, while a Chinese probe was lost along with the Russian Phobos-Grunt mission in January. But Karnik said India shouldn't be concerned with stunts.

"My only concern, if anything, is not the risk of failure," he said. "It's the risk that the program should not get diverted to these high-visibility, somewhat prestige-related events."

Y'all realize this sinkhole started on August 3rd, right? And that the sinkhole hasn't expanded since August 10th, right? Don't know why this story has suddenly become big news on WU.

They don't know what has caused the rupture. Maybe a drilling company, maybe a quake, maybe the salt dome was not strong enough. Rumbling was heard.
article says:
initially estimated the area was about 200 feet by 200 feet on private land near the Texas Brine Co. LLC facility. in speaking with the Louisiana Department of Natural Resources and the Governor's Office, there was a risk that the slurry area could grow to a size of about 2,000 feet across.

authorities are concerned that if the slurry area expands to that extent, it could affect natural gas, water and other wells working the nearby Napoleonville salt dome.

Kids in Israel must feel like kids did during the 70's and 80's here in the states. As a young boy in the early 80's, I remember very acutely walking outside and wondering if the world was about to end. Action to be taken within 60 by Israel and most likely the West too, implications couldn't be higher.

Umm...huh? Louisiana has suddenly expanded to include to include 63% of the nation's hay acreage and 73% of the cattle acreage? Louisiana is 38th among the 50 states in hay production.

Tropical Cyclone Bulletin

Here is the latest Tropical Cyclone Bulletin issued by the Hong Kong Observatory.

The Strong Wind Signal, No. 3 was issued at 1:40 p.m.

This means that winds with mean speeds of 41 to 62 km/h are expected.

Kai-tak was estimated to be about 370 kilometers south-southeast of Hong Kong and is forecast to move west-northwest in the general direction of the coast of western Guangdong.

Winds were strengthening gradually in the past few hours. Although Kai-Tak is tracking westward.
