HOUSTON (AP) — Harvey continues to head back toward the Gulf of Mexico at a slow pace.

The National Hurricane Center says in its 4 a.m. CDT update that the tropical storm that made landfall late Friday as a Category 4 hurricane, dropping heavy rain in the Houston area, still has sustained winds of up to 40 mph (65 kph) and is centered 20 miles (30 kilometers) east of Victoria, Texas, about 120 miles (193 kilometers) southwest of Houston. It continues to creep to the southeast at 3 mph (4.8 kph).

That means it remains virtually stalled near the coast and continues to drop heavy rain on the Houston and Galveston areas. In the past 48 hours, numerous spots in the region have measured more than 25 inches (64 centimeters) of rain.

The hurricane center says Harvey's center was expected to drift off the middle Texas coast on Monday and meander offshore through Tuesday before beginning "a slow northeastward motion." The center says those in the upper Texas coast and in southwestern Louisiana should continue to monitor Harvey's progress.
