Officials say another person has died in Houston-area floods, raising the toll to eight.

The Austin County Sheriff's Office didn't provide more information Wednesday on the most recent drowning.

Six people have died in Harris County and one more in neighboring Waller County since a huge storm dropped more than a foot of rain on the area. Thousands of people have been evacuated from their homes and major highways were closed after the rains that started Sunday overwhelmed Houston's bayous.

Forecasters have issued another flash flood watch for Houston through Wednesday night.

The Houston Independent School District has resumed classes after being closed for two days because of the flooding.

Elsewhere, authorities blamed heavy rains for a sinkhole that opened up on a residential street in northwest Dallas.
