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.
