Hurricane Hunters reveal 4 warning signs that a storm is about to strengthen

Nearly three decades of Hurricane Hunter data reveal four features that can help a tilted tropical cyclone straighten its circulation and become capable of intensifying. The findings could give forecasters an earlier warning that a seemingly disorganized storm is becoming primed to strengthen. Hurricane Hunters reveal 4 warning signs that a storm is about to strengthen.

Hurricane Hunters reveal 4 warning signs that a storm is about to strengthen Science News from research organizations Hurricane Hunters reveal 4 warning signs that a storm is about to strengthen Scientists have identified four clues that could reveal when a tilted tropical cyclone is about to straighten up and become capable of rapidly strengthening. 21, 2025, reaching Category 5 strength by Oct. That means the storm’s rotating centers at different levels of the atmosphere must line up rather than remain tilted away from one another.

Using nearly three decades of observations from NOAA Hurricane Hunter aircraft, researchers have now identified four features that appear to help tilted tropical cyclones become vertically aligned and more capable of intensifying. The research was led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, working with colleagues at NOAA’s Atlantic Oceanographic and Meteorological Laboratory. Their findings suggest that successful alignment depends on several factors working together, including the storm’s internal structure, the direction of surrounding winds, and environmental conditions around the cyclone.

Understanding this transition is important because rapidly intensifying storms can give coastal communities and emergency managers very little time to respond.
