SAN FRANCISCO - At least eight people have died as of Tuesday morning after Hurricane Beryl made landfall in southern Texas, the United States, leaving nearly three million homes and businesses without power, authorities said.

Beryl hit the US states of Texas and Louisiana on Monday. Officials said seven people had died in Texas's Harris and Montgomery counties, while one death was confirmed in Louisiana.

More than 1,100 flights were canceled at Houston's main airport on Monday, according to flightaware.com.

Some 2.3 million customers in Texas were experiencing a power blackout as of Tuesday morning, down from a peak of over 2.7 million on Monday, according to poweroutage.us.

Beryl has been downgraded to a tropical depression from a Category 1 hurricane. It is expected to move from Arkansas through Michigan throughout the week. Flash flooding and heavy rain remain a risk, according to the National Hurricane Center.
