MESOCYCLONE-INDUCED DOWNBURSTS ASSOCIATED WITH THE LANDFALL OF HURRICANE IRENE (1999) OVER SOUTH FLORIDA
Stacy R. Stewart, NOAA/AOML/NHC/TPC, Miami, FL; and C. Robbins
As the center of Hurricane Irene passed over South Florida on 15-16 Oct 1999, a series of damaging downbursts occurred in the vicinity of Lake Okeechobee in association with outer convective bands and eyewall convection in the northwest quadrant of Irene's wind field.
Ground-based Doppler radar data indicate that the strong wind gusts (26-43 m/s)were likely induced by mid-level mesocyclones associated with localized strong convective cells, and some of the more intense mesocyclones may have reached down to the surface as small tornadoes or "mini-swirls".
