Tornado Hits Denver International Airport

Tornadoes are difficult to observe, since they rarely move over instruments that can directly measure their winds. A rare exception occurred on Tuesday, when an EF-1 tornado obligingly ran directly over the weather station at Denver International Airport, which recorded a wind gust of 97 mph. Remarkably, the weather station was not destroyed, and continued to transmit data after the tornado had passed. There was no major damage reported at the airport.

The tornado was only five miles from the Terminal Doppler Weather Radar at the airport, allowing a unique up-close view of the precipitation-free doughnut hole where the tornado was. The tornado was about 100 - 200 yards wide.

Caribbean Disturbance Little Threat to Develop

Posted by: Dr. Jeff Masters, 2:20 AM GMT op 16 juni 2013

+56

A concentrated area of heavy thunderstorms has developed over the Southwest Caribbean near the coast of Nicaragua in association with a tropical wave that is moving slowly west northwest towards Nicaragua and Honduras. Wind shear is a high 20 - 30 knots, which will keep any development slow. The high shear is due to the presence of the subtropical jet stream, which is expected to push northwards over the next few days. This may allow wind shear to fall to the modera...
