Tropical Storm Harvey Has Stalled - Catastrophic Flooding Still Forecast For South Texas!
Valid At 5:29 PM MDT This Saturday Afternoon.
Its hard to fathom just how bad conditions are forecast to become across parts of south and southeast Texas over the five days or so. Most people simply don't understand the consequences of what happens when you unload this much water (rain) from the atmosphere over such a large expanse of countryside. In fairness how can they? If the computer forecast models are correct on the forecast rainfall totals from Harvey over next several days to nearly a week ahead, then that part of our nation will see flooding that most people who live there have never seen in their lives! Forecast models are holding fast with their forecasts of an additional 15 to 30 inches of rainfall with isolated locations possibly seeing 40 inches or more, and this on top of the 5 to 17 inches that has already fallen.
This is one of those times when many people are praying and hoping the models are wrong.

Tropical storm force winds will continue to impact portions of South Texas generally east of Highway 281 and over the coastal waters for tonight. Catastrophic life-threatening flooding is still expected due to the heavy rainfall that is expected over the next several days. Storm total rainfall accumulations will be as much as 15 to 30 inches of rainfall with isolated 40 inches across eastern portions of South Texas, mainly east of a line from Beeville to Port Aransas. West of that area up to Highway 16, generally 5 to 15 inches of rainfall will be possible. West of Highway 16, generally 5 inches or less of rainfall is expected. Storm surge inundation will remain from 4 to 7 feet from Port Aransas to Port Lavaca tonight. Flooding from storm surge inundation will gradually subside by Sunday.

POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Potential impacts from the flooding rain are still unfolding across the Coastal Bend and Victoria Crossroads area, mainly east of Highway 16. Remain well guarded against life-threatening flood waters having possible catastrophic impacts. If realized, these impacts include: - Extreme rainfall flooding may prompt numerous evacuations and rescues. - Rivers and tributaries may overwhelmingly overflow their banks in many places with deep moving water. Small streams, creeks, canals, and ditches may become raging rivers. Flood control systems and barriers may become stressed. - Flood waters can enter numerous structures within multiple communities, some structures becoming uninhabitable or washed away. Numerous places where flood waters may cover escape routes. Streets and parking lots become rivers of raging water with underpasses submerged. Driving conditions become very dangerous. Numerous road and bridge closures with some weakened or washed out. * SURGE: Impacts from the surge event are now unfolding across the Middle Texas coast between Port Aransas and Port Lavaca. Tide inundation levels will continue to be from 4 to 7 feet AGL. Remain well away from life-threatening surge having additional extensive impacts. If realized, these impacts include: - Large areas of deep inundation with storm surge flooding accentuated by battering waves. Structural damage to buildings, with several washing away. Damage compounded by floating debris. Locations may be uninhabitable for an extended period. - Large sections of near-shore escape routes and secondary roads washed out or severely flooded. Flood control systems and barriers may become stressed. - Severe beach erosion with significant dune loss. * WIND: Potential impacts from the main wind event are now unfolding across the Victoria Crossroads into the Coastal Bend. If realized, these impacts include: - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. Elsewhere across SOUTH TEXAS, little to no impact is anticipated. * TORNADOES: Potential impacts from tornadoes are still unfolding across the Victoria Crossroads. If realized, these impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Elsewhere across SOUTH TEXAS, little to no impact is anticipated.
