HOUSTON (AP) - The National Hurricane Center says tide gauges off the coast of Texas indicate that storm surge is already occurring near Corpus Christi and Port Aransas.
That news comes as the National Hurricane Center says Harvey has strengthened to a Category 4 storm.
The center says Harvey has maximum wind speeds of 130 mph as the powerful storm churns off the Texas coast. Forecasters are labeling it a "life-threatening storm."
It's forecast to make landfall on the mid-Texas coast late Friday or early Saturday.
Forecasters are labeling it a "life-threatening storm" with landfall predicted late Friday or early Saturday between Port O'Connor and Matagorda Bay, a 30-mile (48-kilometer) stretch of coastline about 70 miles (110 kilometers) northeast of Corpus Christi.
Texas officials have been expressing concern that not as many people are evacuating compared with previous storms as Hurricane Harvey bears down on the state.
