50th Anniversary of Hurricane Camille

On the night of August 17-18th, 1969, Hurricane Camille came howling into Waveland, MS, with estimated sustained winds of 175 mph (280 km/hr) and a storm surge of 24 feet (7.3 m) to become the second strongest hurricane on record to make landfall in the United States (after the Labor Day Hurricane of 1935).  Camille also … Continue reading 50th Anniversary of Hurricane Camille

Hurricane Field Program Update — Tuesday, August 20, 2019

HRD successfully completed their last research NOAA P-3 mission into Invest 95E, located in the East Pacific, today collecting valuable data that will help towards better understanding how tropical storms develop. The data from the flight reveals the complicated circulation structure in developing storms and their link to precipitation (rainfall) processes, which are critical to … Continue reading Hurricane Field Program Update — Tuesday, August 20, 2019

Hurricane Field Program Update — Monday, August 19, 2019

HRD and the NOAA Hurricane Hunters successfully flew the first hurricane formation (aka, genesis) research mission out of Costa Rica yesterday into the disturbance identified as Invest 95E by the National Hurricane Center (NHC). The NOAA P-3 (NOAA42, “Kermit”) flew a complete “lawnmower” pattern encompassing the broad circulation observed in the Invest. HRD has tasked […]

Hurricane Field Program Update — Saturday, August 17, 2019

HRD has tasked the NOAA P-3 (NOAA42, aka "Kermit") to fly research missions into a potentially developing storm in the East Pacific, currently identified as Invest 95E by the National Hurricane Center. The P-3 ferried down to Costa Rica yesterday. Operating missions out of Liberia, Costa Rica, the goal of our research missions will be … Continue reading Hurricane Field Program Update — Saturday, August 17, 2019
