Harvey May Spare Houston Heavy Rain: Hour-By-Hour Weather Forecast

HOUSTON, TX — The latest forecast models indicate Tropical Storm Harvey may not wallop the Texas Gulf Coast as hard as originally expected when it makes landfall Tuesday. The powerful storm system hovering over the Houston area is expected to bring heavy rains overnight, but the rain threat may be gone in Houston by Wednesday morning.

A shift in the storm’s path won’t end the misery in the Houston area, where some areas have received more than 40 inches of rain since Hurricane Harvey made landfall Friday night as a Category 4 storm. The epic and catastrophic flooding is expected to force 30,000 people across Texas and Louisiana from their homes, and at least 5,500 Houstonians are in shelters.

Though the new path of the storm spares Houston, an additional 4 to 8 inches of rain is possible, with locally higher amounts. David Paul, the chief meteorologist for KHOU-TV, said that while the worst of the rain may be over for Houston, heavier rains will be moving to the east.

Power outages and localized storm surges are possible, mainly along intermediate shorelines and in low-lying spots or areas farther inland where higher surge waters move ashore.
