Analysis | What it was like to fly into Hurricane Melissa’s eye
I was sitting in the middle of a 10-mile-wide stadium of the gods. On all sides, hulking thunderstorms towered high above. Just miles in any direction, a hellish-monster creating unsurvivable conditio...

It’s peak hurricane season. 75 percent of all tropical cyclone activity occurs between August 20 and October 20.
The season has been quiet for the U.S. so far, but that could change in mid-September.

Imagine getting hit by two tornadoes in just 41 minutes. That’s what happened near Bassfield, MS on March 15. During the high risk outbreak, overlapping tornado paths struck the same area—an intense and rare event caught on radar and maps.

There is a slight chance of a bit of #thundersnow in NYC as a bit of elevated instability, or thunderstorm fuel at the atmosphere’s mid levels, works through.
