00Z HRRR forecasted flat ice accumulations are downright scary. Maximum ice corridor from TX to TN and another maximum in N GA through S Appalachia look to be areas that will see the worst of it with extensive tree & power grid damage. These areas also tend to have high socioeconomic vulnerability.

Hurricane Melissa produced the fastest hurricane winds to be recorded by a dropsonde, verified by reviewing data at NSF NCAR! Hurricane Melissa’s 252 mph wind gust surpassed the previous record from Typhoon Megi over the Western Pacific in 2010, where a dropsonde measured wind gusts of 248 mph.

Rapid versus slow intensification of idealized tropical cyclones using soundings from reanalysis
Climatologically averaged environmental wind and moisture around intensifying tropical cyclones are used in an idealized model to further discriminate differences between ensembles of rapidly (RI) an....
