Microwave satellite imagery has revealed that Tropical Storm Mirinae is strengthening enough to develop an eye, and that's what it's doing. Mirinae was formerly Tropical Depression 23W, but became a tropical storm and received its name.Tropical Storm Mirinae had maximum sustained winds near 52 mph on Tuesday, October 27 at 1200 UTC (8 a.m. EDT). It was located about 205 nautical miles northwest of Guam, so all of the watches and warnings for Guam have been discontinued. Its center is near...

BETHEL, Conn., Sept. 21, 2009 /PRNewswire/ -- Driven by research that shows thunderstorms and tornadoes during fall months pose one of the greatest weather threats to power outages, Duracell picked the first day of autumn to launch its "More Power To Protect" program, pledging more than 10 million hours of battery power to communities most susceptible to these occurrences. (Photo: http://www.newscom.com/cgi-bin/prnh/20090921/CL78461) To help launch the campaign, Duracell has joined forces...
Marty is struggling to hold onto tropical storm status, and things are just going to get worse for him, as he moves into an area with stronger wind shear. Infrared satellite imagery from NASA's Aqua satellite showed that Marty's thunderstorm cloud tops are not as cold as they were earlier today, September 17, and his cloud pattern has become a little less organized.Infrared imagery from NASA's Atmospheric Infrared Sounder (AIRS) indicates Marty's cloud tops have warmed slightly, indicating...
A freak bolt of lightning struck a 56-year-old cyclist in Englewood, Colo., even though no electrical storms were reported in the area, authorities say.Perry Schellpfeffer, an Englewood police spokesman, told The Denver Post the unidentified victim was hit by the lightning Wednesday afternoon. His injuries were not considered life-threatening.There were some clouds and it was thundering a little, but there wasn't any kind of lightning storm, Schellpfeffer said.Among U.S. states, Colorado tied...
GENEVA, August 31 /PRNewswire/ -- The dataset will provide lightning information throughout the globe to serve the world's meteorological institutions and other weather-dependent users. Consisting of lightning sensors distributed throughout the globe, the coverage and performance of Vaisala's Global Lightning Dataset (GLD360) is unique, global, and real-time. GLD360 outperforms satellite lightning detection by enabling uniform global coverage and by providing the timeliest...
Duke University researchers have captured images of lightning bolts shooting upwards.The rare phenomenon, known as "gigantic jets," was photographed during tropical storm Cristobal last year.The gigantic jets shot more than 40 miles high, Duke Professor Steven Cummer and colleagues wrote in the journal Nature Geoscience. "Despite poor viewing conditions as a result of a full moon and a hazy atmosphere, we were able to clearly capture the gigantic jet," said Cummer."What we were able to...
A 38-year-old bricklayer in the British town of Kettering says he is lucky to have survived being struck by lightning while walking his dogs. The Daily Mail Monday said Brad Gifford was hit by a 300,000-volt bolt of lightning while attempting to seek shelter from a thunderstorm by ducking under a tree. Gifford suffered burns to 11 percent of his body and both of his eardrums were burst. Nonetheless, he expressed relief at having survived the potentially deadly lightning strike, the newspaper...
One person was killed and 15 others injured when a stage collapsed at the Big Valley Jamboree festival in Camrose, Alberta, emergency officials said. The stage buckled Saturday as a large storm swept through area, the Edmonton (Alberta) Journal reported Sunday. An unknown number of people were trapped in the wreckage of the stage following the collapse, the Journal said. Their conditions as of Sunday were not reported. Severe weather Saturday also prompted the evacuation of the Heritage...
NASA is funding the development of a prototype system to provide aircraft with updates about severe storms and turbulence as they fly across remote ocean regions.Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., in partnership with colleagues at the University of Wisconsin, are developing a system that combines satellite data and computer weather models with cutting-edge artificial intelligence techniques. The goal is to identify and predict rapidly evolving...

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...
Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
In this lesson we are going to take a look at super-cell thunderstorms and what they mean and how they impact our daily lives. First, a super-cell thunderstorm is formed from a cumulus-nimbus cloud. Super-cell thunderstorms are the most advanced form of thunderstorms known on earth. This is because these types of thunderstorms need so many things to come together in the atmosphere at the same time. The first thing they need is the warm moist air at or near the surface. Secondly, is...
Orographic thunderstorms are formed when the air is pushed up a mountain side. This type of thunderstorm is found only on the windward side of a mountain range. In the United States we would find these types of thunderstorms on the western slopes of the Rocky Mountains and also on the western slopes of the Appalachians. Things that make this thunderstorm important: First of all they only form in certain geographical places on the earth as mentioned above. But they can form anywhere in the...
September 5: The southwest was encompassed in the monsoon rains yesterday bringing areas of flash flooding to portions of Arizona. Another smaller but large flooding event occurred along the Mississippi Gulf Coast where places in Jackson County received 7inches of rainfall in 2 1/2hours which lead to large flooding problems of already saturated grounds from Isaac-1. The heat persisted in Eastern Texas and into Louisiana and northward into Arkansas as some places felt temps hit the100’s with...
