Hurricane Hunters Pinpoint Dean

KEESLER AIR FORCE BASE, Miss.-- --  The Air Force Reserve Hurricane Hunters are currently deployed to St. Croix in the U.S. Virgin Islands where they are flying state-of-the-art WC-130J aircraft into Hurricane Dean in support of the National Hurricane Center.

Hurricane Dean blasted its way into the Caribbean uprooting trees, downing power lines and damaging homes and other structures on St. Lucia today as it spun into the Caribbean on a track that could take it near Jamaica as a powerful storm next week.

The Hurricane Hunters recorded Dean's minimum central pressure at 28.387 inches, moving toward the west at 22 mph, with sustained winds increasing to 125 mph. Dean is a major Category 3 hurricane on the Saffir-Simpson scale. The National Hurricane Center expects the storm to affect Puerto Rico and The Dominican Republic, dousing them with up to five inches of rain. Another reconnaissance mission is scheduled for tonight and the unit will continue rotating aircraft through the storm until it is no longer a threat.

The 2007 season started with Sub-Tropical Storm Andrea on May 9. Since then, the season has been slow, which has allowed more aircraft to be equipped with the Stepped- Frequency Microwave Radiometer, affectionately called the 'smurf'.

Hurricane Hunters are using the 'smurf' technology on flights in to Hurricane Dean. The 'smurf' allows the Citizen Airman of the Hurricane Hunters to constantly measure surface winds directly below the aircraft. The 'smurf' can also determine rainfall rates within a storm system. This, in addition to wind speeds at flight level provides structural detail of the storm.

"The SFMR will be the biggest advance I can think of to improve hurricane intensity forecasts," said Max Mayfield, former director of the NHC.

The data collected by the Hurricane Hunters increase the accuracy of the NHC forecast by 30 percent, a rate which will undoubtedly increase with the use of the 'smurf.' This data enables the NHC to more accurately predict the path of storms in order to save lives and narrow areas of evacuation, according to NHC forecasters.

One WC-130J aircraft will be equipped with the SFMR each month until all 10 WC-130J aircraft are outfitted with the SFMR pod.
