just south of the Houston, TX area, during the evening. The tornadoes have
caused some damages to some signs and buildings. I haven’t heard about any
reports of flooding anywhere in, or near the Houston, TX area. Just some wet

Rain bands from Harvey were moving onshore the Upper Texas coastal areas at 4:00 PM. See the latest hurricane local statement and flash flood watch for details on the watches and warnings. Here are expected threats from Harvey expected for tonight across Southeast Texas: * Isolated tornadoes * Tropical storm-force wind gusts in rain bands * Bands of locally heavy rainfall especially along the coastal counties The potential for copious amounts of rainfall exists with Harvey over the next five days with the storm total potential of 15 to 35 inches and isolated maximum amounts of 40 inches through next Wednesday. Rainfall of this magnitude will cause catastrophic and life-threatening flooding! Harvey is caught in a weakness in the upper level subtropical ridge of high pressure. The lack of steering winds aloft is one of the major factors to the rainfall potential. There is a possibility that the storm or its remnants will be over or near Southeast Texas through Thursday of the upcoming week. It cannot be stressed enough that the main threat from Harvey to Southeast Texas is inland flooding from prolonged periods of heavy rainfall. 40 MARINE... Marine impacts from Harvey for tonight include: * Tropical storm-force winds. * Coastal flood threat from elevated tides. * Reasonable worst case surge: extending miles inland in places in from Brazoria to Matagorda. * Very strong to extreme rip currents and high surf. Discharge from elevated rivers and continued elevated water levels may continue to impact navigation through the weekend into early next week. && .AVIATION... Will be keeping with the slow/steady ramping up of winds and wind gusts for the SE TX TAFs...with the higher speeds at sites closer to the center of Hurricane Harvey (down southwest toward the mid- dle TX coast). With this system expected to stall/linger over the region (after landfall), we will transition to a rather prolonged heavy rain event in the coming days.

The rainbands will become more widespread through tonight. Storm surge of 4 to 6 plus feet will affect the coast. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Tropical storm force winds may occur along the Brazoria County coast line as early as late Friday afternoon and persist through Saturday afternoon. Gusty...primarily under tropical force winds...will likely spread inland early Saturday morning and persist through early Saturday afternoon. Storm surge heights will range from between 4 to 6 feet along the Gulf coast...1 to 3 feet around Galveston Bay...above ground level with rising water levels occurring from as early as late tonight and persisting through Saturday. Total rainfall amounts over the next several days will range from 15 to 35 inches to localized near 40 inches. Rainfall of this magnitude will cause catastrophic and life-threatening flooding. Isolated tornadoes will also be possible within Harvey`s outer thunderstorm bands. 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 areawide flooding. .SPOTTER INFORMATION STATEMENT... Spotters will be needed from today through the weekend. $$
Hurricane Local Statement

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 are possible through around noon Saturday for the southwestern portions of Southeast Texas. With the strongest winds tonight, storm surge will peak overnight and be slow to recede through Sunday. Elevated tide levels will continue through Tuesday. Tornadoes will continue to form overnight tonight, especially across the coastal counties. 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 over the coming 3 to 5 days. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Potential impacts from the flooding rain will be unfolding across the southern half of Southeast Texas over the next 3 to 5 days. 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. Potential impacts from the flooding rain will be unfolding across the northern half of Southeast Texas over the next 3 to 5 days. Remain well guarded against life- threatening flood waters having possible limited to extensive impacts. * SURGE: Potential impacts from the main surge event are now unfolding across the Upper Texas Coast, primarily west of Freeport. The Matagorda Ship Channel has risen one foot in the last 15 minutes. Remain well away from life-threatening surge having additional devastating impacts. If realized, these impacts 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. Potential impacts from the main surge event are also now unfolding across the Upper Texas Coast east of Freeport including Galveston Bay. Remain well away from locally hazardous surge having additional limited to significant impacts. * WIND: Potential impacts from the main wind event are now unfolding across Matagorda Bay. Remain well sheltered from life-threatening wind having possible devastating impacts. If realized, these impacts 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. Potential impacts from the main wind event are also now unfolding across the southwestern portion of Southeast Texas. Remain well sheltered from life-threatening wind having possible limited to extensive impacts. * TORNADOES: Potential impacts from tornadoes are still unfolding across Southeast Texas, especially along the coastal counties. Remain well braced against a tornado event having additional limited impacts. 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. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Do not return to evacuated areas until hazardous winds diminish and flood waters abate. * OTHER PREPAREDNESS INFORMATION: Now is the time to remain safely sheltered from the storm. Stay inside and away from windows. Listen for updates and be ready in case you lose electrical power. Locate your battery powered radio and flashlight from your Emergency Supplies Kit. Keep these items close. During the peak of the storm, keep your shoes on and rain gear handy. Boots and tennis shoes offer the best foot protection if you become unexpectedly exposed to the elements. Continue to keep your cell phone well charged for as long as possible. If you lose power, use it more sparingly and mainly for personal emergencies and check-ins. Do not overload communications systems with idle chatter. Do not venture outside while in the eye of a hurricane. Within the eye, weather conditions may temporarily improve which can be misleading. Once the eye passes, the wind will change direction and return to dangerous speeds. Heavy rain will also return. Be smart and remain safely hidden from the storm. Do not be a thrill seeker or risk your life for senseless photos or videos. Be wise and avoid becoming another statistic. Be ready to move to the identified safe room if your home or shelter begins to fail. Quickly move to an interior room on the lowest floor. Put as many sturdy walls between you and the storm as you can. Protect your head and body. When major hurricanes make landfall, extreme winds bring a tremendous threat to life and cause devastating to catastrophic damage. During landfall, listen for extreme wind warnings which indicate the exact timing and location of these incredible life-threatening winds. If issued for you area, move to the safest place within your home or shelter. Take the same life-saving actions as if it were a violent tornado. * 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 NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Houston/Galveston TX around 430 AM CDT, or sooner if conditions warrant. $$Storm Surge Watch
