NHC designated this disturbance Invest 96L on Wednesday morning--the first "Invest" of the year for an African tropical wave, and something we'll see a lot more of as once the Atlantic hurricane season hi...

Extreme 'Grey Swan' Hurricanes in Tampa Bay: a Potential Future Catastrophe

A “black swan” hurricane—a storm so extreme and wholly unprecedented that no one could have expected it—hit the Lesser Antilles Islands in October 1780. Deservedly called The Great Hurricane of 1780, no Atlantic hurricane in history has matched its death toll of 22,000.

Darby Falling Apart as it Makes Landfall on Hawaii's Big Island

By: Jeff Masters, 10:57 PM GMT on July 23, 2016

Tropical Storm Warnings are flying for the Big Island of Hawaii, Maui and Oahu as Tropical Storm Darby dashes itself against the high mountains of the Big Island. Saturday evening satellite loops showed that Darby was becoming misshapen and disorganized as it made landfall on the Big Island, and radar on the Big Island showed a highly asymmetric storm, with all of the heavy rains confined to the southeast side.
