U.S. residents living on the Gulf Coast are hitting grocery stores searching for water and other essentials before a potentially life-threatening hurricane makes landfall.

The National Weather Service forecasts Tropical Storm Harvey will be upgraded to a major hurricane by Friday, “bringing life-threatening storm surge, rainfall, and wind hazards to portions of the Texas coast.”

“Life-threatening flooding is expected across much of the Texas coast from heavy rainfall of 12 to 20 inches,” reports the NWS, with some areas reportedly expected to receive 30 inches.

A photo from a Sam’s Club in Corpus Christi depicts a long check-out line full of people, with a caption reading, “Waiting to buy water for #Harvey.“

Photos from Houston’s ABC13 show empty shelves at several grocery stores.

People on Twitter described “fights” over water, with some likening the chaos to Black Friday.
