Rapid intensification is defined as a tropical cyclone intensifying by at least 35 mph within a 24-hour period, typically occurring when a storm encounters a conducive environment of warm water, low wind shear, and high mid-level moisture.
According to the NHC, as of Friday afternoon, the highest wind speed that Debby is forecast to attain is 65 mph, which is still below the 74-mph threshold needed to achieve hurricane status.
Preparing for the Storm
Despite the storm not yet being fully organized, forecasters are advising residents to be prepared. AccuWeather meteorologist Paul Pastelok emphasized, “Residents from Louisiana to Florida’s west coast have to be ready in case it rapidly intensifies.”
The National Weather Service (NWS) in Tampa has also issued guidance, stating that “for now, the bottom line is to monitor the progress of this system, and check your hurricane preparedness plan.” With heavy rain in the forecast, the NWS advises residents to “consider your vulnerability to flooding.”
Understanding Tropical Waves
A tropical wave, as defined by the National Weather Service, is an elongated area of low pressure or cyclonic curvature maximum moving east to west across the tropics. Also known as an easterly wave, these systems can lead to the formation of a tropical storm.
