The National Hurricane Center says Hurricane Harvey has strengthened to a Category 3 storm and could produce nearly as much rain as Seattle sees all year.
Some areas of Texas are forecast to see as much as 37.49 inches of rain – Seattle’s average yearly rainfall. Parts of the Texas coast are slated to see 30-35 inches of rain.
The center says Harvey has maximum wind speeds of 120 mph as the powerful storm churns off the Texas coast. Forecasters are labeling it a "life-threatening storm."
The storm quickly grew Thursday from a tropical depression into a Category 1 hurricane, and then developed into a Category 2 storm early Friday. By Friday afternoon, it had become a Category 3 storm. It's forecast to make landfall in Texas late Friday or early Saturday.
The slow-moving storm is fueled by warm Gulf of Mexico waters. 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.
