7 Hurricane Hunters identify four warning signs of tropical cyclone intensification¶

Scientists at the University of Miami and NOAA identified four warning signs indicating when a tilted tropical cyclone is becoming primed to strengthen, based on nearly three decades of Hurricane Hunter observations. The findings could enable forecasters to give coastal communities additional lead time for evacuation decisions.

Nearly three decades of NOAA Hurricane Hunter data analyzed
Four characteristics: compact tightly organized circulation, favorable tilt relative to wind shear, stronger rising air and rainfall near lower center, warm water with abundant moisture and weak middle-level winds
Tropical cyclones must become vertically organized before substantial intensification
Strong upper-level winds prevent strengthening until circulation centers realign
