Hurricane Field Program Update – Wednesday, October 10, 2018

The NOAA P-3 completed its last mission into Hurricane Michael this morning, passing through the storm four times. As in the previous three missions, we provided critical measurements of the 3-D wind, precipitation, and thermodynamic (temperature and humidity) structure of the storm from our Doppler radar, dropsondes, and flight level measurements. The data was not …

30th Anniversary of Hurricane Gilbert

On September 16, 1988, Hurricane Gilbert made landfall at the Mexican city of La Pesca,Tamaulipas, with winds of 125 mph (200 km/hr).  It had already brought destruction upon the Yucatan peninsula and the Caribbean islands.  Along the way it set a new low-pressure record that would stand for 17 years. Gilbert was a classic Cape …
