really strong gusts. (20 to maybe 30 mph) during the heavy to very heavy bands
of rain. There have been more tornadoes and damage reported along with more
flooding in and around the Houston, TX area. Many cars have been stalled out

Day Three. Nothing much has changed. My neighborhood received a pretty good
break from the rain this afternoon, with only some light to moderate rain
bands. Moderately heavy to heavy rain has started up again, this evening, but
doesn’t look to be as bad as last night. There have been a few occasional 20 to
30 mph wind gusts, but other than that the wind speeds have been calm with
gentle to moderate gusts. There have been a lot more flood reports and road
closures in and around the Houston, TX area, with most of the bayous reaching
above flood stage. No flooding has occurred in my neighborhood and hopefully

The center of near-stationary TS Harvey is currently located near Edna, TX and should continue to slowly drift to the south and southeast over the next 24 hours. Rain bands are expected to intensify over night and produce intermittent IFR conditions. Hobby and Intercontinental Airports remain closed to non emergency traffic. TAFs communicate MVFR with periods of IFR conditions within convective banding. Winds are from the southeast and south with occasional gusts to 30 knots inside rain bands. 44 && .PREV DISCUSSION... /ISSUED 516 PM CDT Sun Aug 27 2017/ ..Continued potential for devestating flooding over the next several days from Harvey`s rainfall... DISCUSSION... Rainfall from Harvey continued to produced catastrophic and life- threatening flooding across portions of Southeast Texas this afternoon. Rainfall over the past 48 hours has exceeded 12 inches with a large part of the area receiving in excess of 20 inches. This has led to a long-period flash flood emergency in these locations. Unfortunately, the center of TS Harvey was located just west of Jackson County. Rain bands moving into SE Texas will lead to additional heavy rainfall this afternoon and tonight. The rainfall potential over the next three days is 15 to 25 inches with localized higher amounts. Isolated tornadoes will continue to be a threat in the rain bands to the east of the storm`s center. Stay tuned to the latest advisories on Harvey for the forecast track of Harvey. 40 MARINE... Tropical Storm Harvey is currently in the vicinity of Victoria and is slowly drifting toward the southeast. It is expected to re-emerge over the gulf around Noon on Monday and will remain over the water for a little over 24 hours before it is finally pulled off to the north on Wednesday. The tropical storm warning continues between Port O` Connor and Freeport, and a tropical storm watch has been issued from Freeport to San Luis Pass. Bands of heavy rainfall with embedded thunderstorms will periodically track across the Upper Texas coastal waters...moving in from the south and southwest. Gale force wind gusts and agitated seas will occur in and around any passing strong thunderstorms. Waterspouts will also be a threat within Harvey`s outer bands. East to southeast winds will range between 20 to 30 knots with average wave heights of between 5 to 7 feet...increasing to 20 to 30 knots with 10 to 12 foot seas when the tropical storm moves off the coast. Extreme to strong rip currents will continue for a few more days. Strong currents caused by river discharges into the bays will also be problematic for navigation for at least a few days...possibly into next weekend...given the record setting rainfall that has led to the extreme inland flooding. 44 && .PRELIMINARY POINT TEMPS/POPS...

A catastrophic and life-threatening flash flooding event is unfolding across Southeast Texas this morning. Many Flash Flood Emergencies have already been issued for the Houston Metro area overnight, some of which remain in effect this morning. Bands of heavy rainfall will continue to drop devastating amounts of ADDITIONAL rainfall across the area over the next several days. Tornadoes have also been occurring across Southeast Texas over the last day or so and will continue through the next several days. Coastal flooding may be an ongoing issue along the coast where winds will continue to push water onshore, particularly south of Sargent. Elevated tides will cause the recession of coastal flood waters to be slow, likely lasting into the first part of the week. Wind gusts to tropical storm force are still ongoing, primarily in the southwestern portions of the area towards Matagorda Bay. Though there are currently multiple hazards present across the area, the greatest threat to life and property remains the ongoing extreme rainfall and subsequent prolonged and catastrophic flash flooding. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for life-threatening rainfall flooding having possible devastating impacts across all of Southeast Texas. 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. * TORNADOES: Prepare for 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. * WIND: Prepare for hazardous wind having possible limited impacts across Southeast Texas. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. * SURGE: Prepare for locally hazardous surge having possible limited impacts across the upper Texas Coast. Potential impacts in this area include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. Elsewhere across Southeast Texas, little to no impact is anticipated. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Do not return to evacuated areas until it is safe. Listen for the all-clear signal from local authorities. Stay put stay safe! * 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. 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. 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. 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. 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. * 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 10 PM CDT, or sooner if conditions warrant. $$There were Also more than a few flash flood warnings,and a few tornado warnings.There were just too many of them to post.
