Houston, TX  (AP) Officials say rain from Hurricane Harvey could inundate Houston roads and neighborhoods as early as Saturday night.

Jeff Lindner, a meteorologist with the Harris County Flood Control District, said Friday that two key reservoirs in the flood control system — at the Addicks and Barker dams — are currently near-empty and are in no danger of flooding neighborhoods close by. The district has electronic sensors installed along Houston’s bayous and waterways.

Lindner did not single out neighborhoods in Houston, saying all of the nation’s fourth-largest city and its outlying areas face flooding in a storm as large as Harvey.

Houston is notoriously flood-prone and forecast to receive steady rain for several days into next week.
