Tropical disturbance reemerges northeast of the Caribbean Sea

This hurricane season has been marked by storms — such as Hannah, Laura, Sally, Teddy, Gamma, Delta and Zeta — that have “rapidly intensified,” meaning a gain of at least 35 mph in wind speed in a 24-hour period. Iota, the most recent named storm, doubled that mark in the overnight hours of Nov. 15, when it intensified from a Category 2 hurricane to a Category 4. It dissipated over western El Salvador last week.
