President Joe Biden declared a major disaster in Texas as the state reels from a severe winter storm that initially left millions of people without power amid freezing cold temperatures.

Biden’s action makes federal funding available to communities across 77 counties. Additional disaster designations may be made after further damage assessments.

As of Saturday morning, Texas reported nearly 80,000 power outages across the state, according to tracking website poweroutage.us.

Boil water notices remain in effect across 189 counties after more than 1,300 public water systems have reported disruptions in service due to the weather, affecting more than 15.1 million people, the Texas Commission on Environmental Quality said in a statement Saturday early morning.
