Frustrations are mounting across southeast Texas as residents enter a fourth day of crippling power outages and heat, a combination that has proven dangerous – and at times deadly – as some struggle to access food, gas and medical care.

More than 1.3 million homes and businesses across the region are still without power after Beryl slammed into the Gulf Coast as a Category 1 hurricane on Monday, leaving at least 11 people dead across Texas and Louisiana.

Many residents are sheltering with friends or family who still have power, but many can’t afford to leave their homes, Houston City Councilman Julian Ramirez told CNN. And while countless families have lost food in their warming fridges, many stores are still closed, leaving government offices, food banks, and other public services scrambling to distribute food to underserved areas, he said.
