Hurricane Melissa ravaged southeastern Jamaica when it made landfall there last week, leaving behind evident flooding and deforestation in this imagery from Suomi-NPP.

A strengthening Typhoon Kalmaegi (Tino) nears the Philippines.

Earlier today, Hurricane Melissa transitioned into a post-tropical cyclone. Melissa will continue to weaken as it moves northeast across the Atlantic Ocean, and is forecast to make a close approach near Newfoundland this evening.

Low after low passes through the northeastern Pacific Ocean, with the current one bringing an atmospheric river into the Pacific Northwest.

Hurricane Melissa was one of the strongest hurricanes ever recorded in the Atlantic basin, with winds of 185 mph (300 km/h) at its peak. This view of Melissa at Category 5 strength shows its intensity, as a lightning-packed eye wall circles the center of the storm. (1/8)

Hurricane Melissa spent over three days as a major hurricane, becoming one of the strongest Atlantic storms on record. This loop from Saturday night to Wednesday morning follows Hurricane Melissa during its time as at least a Category 3 storm.
