Are there public tornado shelters in OKC?

No, there are no public tornado shelters in Oklahoma City.

According to the City, this is because of the danger that comes with driving to a shelter during severe weather.

"Many deaths attributable to tornadoes are attributed to being in a vehicle," according to the City of Oklahoma City. "Traffic congestion from hundreds or thousands of other residents trying to get to public shelters could have tragic consequences."

Instead, residents are encouraged to shelter in place.

What is 'gorilla hail?'

You might have seen a new term pop up on social media: gorilla hail.

What does it mean?

Gorilla hail is an imprecise term coined by severe weather storm chaser Reed Timmer to describe very large hailstones. This kind of hail is generated during powerful storms, like the ones forecast for Oklahoma today.

Timmer posted on X, formerly known as Twitter, describing the risk of hail over Oklahoma City and Tulsa, along with other parts of the state.

The National Weather Service forecasted hail up to softball size today.
