(WVUE) - Tropical storm conditions ahead of Hurricane Harvey are beginning to spread onshore and the National Hurricane Center warns of "catastrophic flooding" across portions of southern and southeastern Texas.
National Oceanic and Atmospheric Administration tide gauges near Corpus Christi and Port Aransas indicate storm surge inundation of one to two feet is already occurring.
Mobile viewers can watch the stream watch here.
At 12 p.m., the eye of Hurricane Harvey was located about 100 miles southeast of Corpus Christi, Texas and about 105 miles south-southeast of Port O'Connor, Texas.
Harvey is moving toward the northwest near 10 mph and forward speed is expected to decrease significantly during the next couple of days.
On the forecast track, Harvey will make landfall on the middle Texas coast Friday night or early Saturday.
Harvey is then likely to stall or move slowly near or just inland of the middle Texas coast through the weekend.
Maximum sustained winds are near 110 mph with higher gusts. Hurricane-force winds extend outward up to 35 miles from the center and tropical storm force winds extend outward up to 140 miles from the center of the storm.
A sustained wind of 43 mph and a wind gust to 48 mph were reported near Corpus Christi.
Some strengthening is expected and Harvey is expected to be a major hurricane before it reaches the Texas coast.
The minimum central pressure reported by NOAA and Air Force planes was 947 millibars.
