Paper on updrafts in hurricanes and how they relate to intensity changes released online in Monthly Weather Review

Summary:  NOAA Hurricane Hunter aircraft have a Doppler radar that measures wind through the entire hurricane.  We analyzed these radar data collected in many hurricanes since 2004.  Previous studies found that the location of the fastest upward moving air (what we call updrafts) may tell us how strong the storm will be a few hours …

Lisa Bucci named NOAA Team Member of the Month

Lisa Bucci was honored this month for her courageous work last year during Hurricane Irma. Hurricane Irma was an extremely powerful and catastrophic hurricane -- the most intense storm to strike the U.S. coastline since Hurricane Katrina in 2005. On the morning of September 7, 2017, the NOAA National Hurricane Center (NHC) issued hurricane watches …
