Incredible footage from space shows massive lightning storms in Hurricane Irma

All these flashing yellow dots are lightning storms.

They’re all part of Hurricane Irma.

The storms were tracked by NOAA over a period of 80 hours from September 4th to the 9th.

There’s a lot of lightning around the eye.

This is unusual — hurricanes usually don’t have a lot of lightning.

That’s because the winds are usually horizontal.

Vertical winds are usually needed to make lightning happen.

Irma has been downgraded to a category 4.

But it’s still “extremely dangerous.”

It has sustained winds near 155 mph.

The hurricane has already devastated parts of the Carribean.

It’s expected to hit Florida late Saturday.
