This hazardous weather outlook is for portions of Southeast Texas..

DAY ONE…Today and Tonight Hurricane Harvey is located in the south central Gulf of Mexico. Harvey is still strengthening as he moves northwest towards the middle Texas coast. Periods of scattered showers and thunderstorms will occur through the day as the outer bands of Harvey come ashore.

DAYS TWO THROUGH SEVEN…Saturday through Thursday Gustier winds will persist through Saturday afternoon. Gusty at times…but under tropical force winds…will occur through Saturday afternoon. Total rainfall amounts over the next several days will range from a little over 3 inches to localized near 10 inch amounts further south. Rainfall amounts that exceed 3 inches per hour may induce significant flooding concerns. Isolated tornadoes will be possible within Harvey`s far outer storm bands…with the tornado threat increasing latter tonight and persisting through Saturday afternoon. Harvey is forecast to slowly meander across southeastern Texas through mid week. This slow storm movement increases the probability of a higher frequency of heavy rainfall episodes that will only exacerbate any ongoing areawide flooding.

Hurricane Harvey Local Statement Intermediate Advisory Number 20A 725 AM CDT Fri Aug 25 2017

NEW INFORMATION —————
* CHANGES TO WATCHES AND WARNINGS: – None
* CURRENT WATCHES AND WARNINGS: – A Tropical Storm Warning and Storm Surge Watch are in effect for Chambers and Harris – A Tropical Storm Warning is in effect for Austin, Colorado, Fort Bend, Liberty, Waller, and Wharton – A Storm Surge Warning and Hurricane Warning are in effect for Jackson and Matagorda – A Storm Surge Warning and Tropical Storm Warning are in effect for Brazoria and Galveston
* STORM INFORMATION: – About 220 miles south-southwest of Galveston TX – 26.3N 95.8W – Storm Intensity 110 mph – Movement Northwest or 315 degrees at 10 mph SITUATION OVERVIEW —————— Harvey has continued to strengthen this morning to a high-end category 2 hurricane with maximum sustained winds of 110 mph. Harvey is forecast to continue strengthening and will most likely become a major hurricane today before it makes landfall along the Middle Texas Coast later tonight. The primary impact from Harvey over Southeast Texas remains prolonged significant heavy rainfall that will induce extreme widespread flooding through at least the beginning of next week. Tropical storm force winds, with occasional hurricane force wind gusts, and storm surge will occur along the coast as early as this afternoon and persist through Tuesday. Coastal flooding due to storm surge and wave run up will remain an issue throughout the weekend and into the beginning of next week as strong onshore winds will continue to pile water up along the coastline. Again, the primary emphasis and greatest threat to life and property will be the extreme rainfall amounts that will likely lead to a potentially catastrophic and prolonged flash flooding event. POTENTIAL IMPACTS —————–
* FLOODING RAIN: Protect against life-threatening rainfall flooding having possible devastating impacts across Southeast Texas, particularly along and south of the I-10 corridor. Potential 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: Protect against life-threatening surge having possible devastating impacts across the Upper Texas Coast. Potential impacts in this area include: – Widespread deep inundation, with storm surge flooding greatly accentuated by powerful battering waves. Structural damage to buildings, with many washing away. Damage greatly compounded from considerable floating debris. Locations may be uninhabitable for an extended period. – Near-shore escape routes and secondary roads washed out or severely flooded. Flood control systems and barriers may become stressed. – Extreme beach erosion. New shoreline cuts possible. – Massive damage to marinas, docks, boardwalks, and piers. Numerous small craft broken away from moorings with many lifted onshore and stranded. Also, protect against locally hazardous surge having possible limited impacts across northern Galveston Bay and Trinity Bay.
* WIND: Protect against life-threatening wind having possible devastating impacts across Matagorda Bay from Port O`Connor to Sargent. Potential impacts in this area include: – Structural damage to sturdy buildings, some with complete roof and wall failures. Complete destruction of mobile homes. Damage greatly accentuated by large airborne projectiles. Locations may be uninhabitable for weeks or months. – Numerous large trees snapped or uprooted along with fences and roadway signs blown over. – Many roads impassable from large debris, and more within urban or heavily wooded places. Many bridges, causeways, and access routes impassable. – Widespread power and communications outages. Also, protect against life-threatening wind having possible limited to extensive impacts across the rest of Southeast Texas.
* TORNADOES: Protect against a tornado event having possible limited impacts across Southeast Texas. Potential 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. PRECAUTIONARY/PREPAREDNESS ACTIONS ———————————-
* EVACUATIONS: For those under evacuation orders, leave as soon as practical with a destination in mind. Gas up your vehicle well ahead of time. Be sure that you take all essential materials from your emergency supplies kit. Let others know where you are going and when you intend to arrive. If evacuating the area, stick to prescribed evacuation routes. Look for additional traffic information on roadway smart signs and listen to select radio channels for further travel instructions. Drivers should not use cell phones while operating vehicles. For those not under evacuation orders, understand that there are inherent risks to evacuation (such as traffic congestion, accidents, and driving in bad weather), so evacuate only if necessary. Help keep roadways open for those that are under evacuation orders. If you are exceptionally vulnerable to wind or water hazards from tropical systems, consider voluntary evacuation, especially if being officially recommended. Relocate to a predetermined shelter or safe destination. If evacuating away from the area or relocating to a nearby shelter, leave early before weather conditions become hazardous.
* OTHER PREPAREDNESS INFORMATION: Now is the time to bring to completion all preparations to protect life and property in accordance with your emergency plan. Outside preparations should be wrapped up as soon as possible before weather conditions completely deteriorate. Any remaining evacuations and relocations should be expedited before the onset of tropical storm force wind. If you are relocating to safe shelter, leave as early as possible. If heading to a community shelter, become familiar with the shelter rules before arrival, especially if you have special needs or own a pet. Take essential items with you from your Emergency Supplies Kit. Check the latest weather forecast before departing. Failure to adequately shelter may result in serious injury or loss of life. Always heed the advice of local officials and comply with any orders that are issued. Remember, during the storm 9 1 1 Emergency Services may not be able to immediately respond if conditions are unsafe. This should be a big factor in your decision making. Check-in with your emergency points of contact among family, friends, and workmates. Inform them of your status and well-being. Let them know how you intend to ride out the storm and when you plan to check-in again. Keep cell phones well charged and handy. Also, cell phone chargers for automobiles can be helpful after the storm. Locate your chargers and keep them with your cell phone. In emergencies it is best to remain calm. Stay informed and focused on the situation at hand. Exercise patience with those you encounter. Be a Good Samaritan and helpful to others. If relocating to a nearby shelter or to the home of a family member or friend, drive with extra caution, especially on secondary roads. Remember, many bridges and causeways will be closed once higher winds arrive. Also, if you encounter water covering the road, seek an alternate route. Always obey official road signs for closures and detours. If you are a visitor and still in the area, listen for the name of the city or town in which you are staying within local news updates. Be sure you know the name of the county or parish in which it resides. Pay attention for instructions from local authorities. Closely monitor NOAA Weather radio or other local news outlets for official storm information. Be ready to adapt to possible changes to the forecast.
