SITUATION OVERVIEW —————— Tropical Storm Harvey continues to strengthen as it moves northwest towards the Texas Coast. Harvey is expected to continue to strengthen into a hurricane on Friday before landfall. At this point, Harvey could become a major hurricane before landfall. The primary impact from Harvey remains heavy rainfall and subsequent flooding for southeast Texas. There is also the threat for tropical storm to hurricane force winds and life threatening storm surge along the coast. The most likely arrival time for tropical storm force winds to reach the upper Texas coast is Friday afternoon. POTENTIAL IMPACTS —————– * FLOODING RAIN: Prepare for life-threatening rainfall flooding having possible extensive impacts across the southern half of Southeast Texas. Potential impacts include: – Major rainfall flooding may prompt many evacuations and rescues. – Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed. – Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. Prepare for dangerous rainfall flooding having significant impacts. * WIND: Prepare for life-threatening wind having possible devastating impacts across Matagorda Bay and into Jackson County. 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. * SURGE: Prepare for life-threatening surge having possible devastating impacts across the Upper Texas Coast from Port O`Connor to up the coast to Sargent. 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, prepare for locally hazardous surge having possible limited impacts across from San Luis Pass to Galveston and High Island. Elsewhere across Southeast Texas, little to no impact is anticipated. * TORNADOES: Prepare for a tornado event having possible limited impacts across much of 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. Elsewhere across Southeast Texas, little to no impact is anticipated.

PRECAUTIONARY/PREPAREDNESS ACTIONS ———————————- * EVACUATIONS: WATCH/WARNING PHASE – 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. WATCH/WARNING PHASE – 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. WATCH/WARNING PHASE – 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.

* OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and take necessary actions to secure your home or business. Deliberate efforts should be underway to protect life and property. Ensure that your Emergency Supplies Kit is stocked and ready. When making safety and preparedness decisions, do not focus on the exact forecast track as there are inherent forecast uncertainties which must be taken into account. If you live in a place that is particularly vulnerable to high wind, such as a mobile home, an upper floor of a high rise building, or on a boat, plan to move to safe shelter. Take enough supplies for you and your family for several days. If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low lying or poor drainage area, in a valley or canyon, or near an already swollen river, plan to move to safe shelter on higher ground Always heed the advice of local officials and comply with any orders that are issued. Do not needlessly jeopardize your life or the lives of others. When securing your property, outside preparations should be conducted as soon as possible before conditions deteriorate. The onset of strong gusty winds and heavy rain can cause certain preparedness activities to become unsafe. Be sure to let friends and other family members know of your intentions and whereabouts for surviving the storm. For emergency purposes, have someone located away from the threatened area serve as your point of contact. Share vital contact information with others. Keep cell phones handy and well charged. Be a Good Samaritan and check on those who may not be fully aware of the situation or who are unable to make personal preparations. Visitors to the area should become familiar with nearby surroundings. If you are a visitor, know the name of the county or parish in which you are located and where it is relative to current watches and warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors. Closely monitor NOAA Weather Radio or other local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: – For information on appropriate preparations see ready.gov – For information on creating an emergency plan see getagameplan.org – For additional disaster preparedness information see redcross.org
