000 FXUS64 KHGX 240314 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1014 PM CDT Wed Aug 23 2017 .UPDATE... Further update with storms still ongoing but showing a general weakening trend have raised POPS a little further south down into the Houston Metro for the midnight to 6 am period. Outflow could slowly sag south with weak flow into and across the boundary will probably see mainly showers but a few thunderstorms will probably continue through the remainder of the night. Temperatures also running cooler back in the rain cooled air. Tropics... Still no real changes to the first 72-96 hours but NHC did make some changes to the 96+ hr time period taking the storm westward out of the area but they also stressed that confidence is low at that point which is clearly shown in the forecast cone - very large and nearly circular forecast at the end period. Where it drifts to is still very much in question. 45 && .PREV DISCUSSION... /ISSUED 747 PM CDT Wed Aug 23 2017/ UPDATE... Storms over Brenham to College Station to Madisonville to near Crockett continue to sag southward along the frontal boundary. Heavy rainfall and gusty winds of 20-40 mph the main threat there. Have done a quick update to the forecast for the evening hours. Tropics... Hurricane hunters could not find a tropical storm force winds so Harvey remains a TD. It is drifting very slowly northwest. No changes to the current watches. 45 PREV DISCUSSION... /ISSUED 715 PM CDT Wed Aug 23 2017/ AVIATION... SHRA/TSRA will continue to linger through mid-evening around CLL, UTS, CXO, and IAH with stronger activity resulting in IFR to MVFR visibility restrictions and variable and gusty winds approaching 20 knots. Dry conditions are expected near the terminals overnight with isolated SHRA developing along the coast (near GLS) around sunrise and spreading inland as scattered SHRA/TSRA early afternoon. Otherwise, expect VFR to prevail outside of TSRA/SHRA with winds varying between northeast and southeast at 10 knots or less. Huffman PREV DISCUSSION... /ISSUED 412 PM CDT Wed Aug 23 2017/ DISCUSSION... Monitoring for a Significant Multi-Day Heavy Rainfall Event... The ongoing concern is the impacts of Harvey over the next several days. Of course, this will depend upon the eventual track of the storm. The weakness in the upper level ridge currently over Southeast Texas is not expected to change over the next several days. This could lead to rainfall impacts from Harvey over a multi-day period from late Friday through Monday. If the storm or its remnants slow down after landfall the heavy rainfall potential could continue into Tuesday. The flood threat could be heightened by higher than normal tides along the coast combined with high seas will keep the rivers and bayou system from draining as it would normally drain. Because of this, there is a potential for event-total rainfall to range from 10 to 15 inches with isolated locations receiving 20 inches or more. The locations for the greatest rainfall still looks to be from the Interstate 10 corridor southward to the coast. Timing of the event will depend upon the track of Harvey. As of now, it does not appear that widespread rainfall will occur tonight or Thursday. However, an unsettle airmass due to the shearing out upper low over the far northwestern Gulf this afternoon will keep at scattered showers and thunderstorms in place on Thursday. The coverage will then become more widespread on Friday particularly over the southern half of the forecast area. Widespread rain chances are then expected on Saturday, Sunday, and Monday. The forecast after Monday will depend upon where Harvey or its remnants travel. The GFS and ECMWF show that the system will be in between two upper level high pressure areas--a rather concerning pattern for Southeast Texas. 40 MARINE... Marine fcst is obviously tied to the evolution of Harvey. We should start seeing some swell arrive in the coastal waters Thursday, probably building to SCA criteria Thurs night...followed by a continuing wind/sea/surge/tide increase and wx conditions into landfall. Water levels will remain elevated & hamper inland precip drainage probably thru the weekend into early next week. Best estimate of marine related impacts & decision points based on what we currently know: * Onset of 7+ foot seas: Thurs night * Onset of tropical storm force winds within 20 NM - Friday * Onset of hurricane force winds (if any) - Fri night * Onset of coastal flood threat - Thurs night * Reasonable worst case surge: 4-6 feet above ground near landfall, 2-4 feet further away * High risk of rip currents and building surf thru the day Thursday. * Discharge from elevated rivers after landfall may continue to impact navigation. 47 && .PRELIMINARY POINT TEMPS/POPS...

Environmental conditions are favorable for development, and a tropical depression or tropical storm is very likely to form today or tonight. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday The tropical system will move into the northwestern Gulf of Mexico on Friday, and possibly slow down over the region. A slow moving tropical system such as this can produce copious tropical rainfall amounts. In the past, slow moving tropical systems have produced amounts in excess of 20 inches leading to widespread dangerous flooding. Tropical storm to hurricane force winds could be possible, as well as tornadoes and storm surge. High tides along the upper Texas Coast will likely cause impacts from dangerous rip currents to storm surge flooding. The range of possibilities with storm surge are varied given the highly uncertain track of this system. Evacuations may be possible. Marine impacts will include high winds and large dangerous seas possible by Friday again depending on the strength and track of the system. Persons in Southeast Texas should be monitoring the weather closely. .SPOTTER INFORMATION STATEMENT... Spotter activation is likely at some point between Thursday night and Monday. $$

TD Harvey is expected to continue to strengthen into a tropical storm or hurricane during the next couple of days. The primary impact from Harvey remains heavy rainfall and subsequent flooding, but there will still be a threat for tropical storm to hurricane force winds and storm surge along the coast. The most likely arrival time for Tropical Storm force winds to reach the Upper Texas Coast is during the day on Friday. Harvey is forecast to remain somewhere in the vicinity of S to SE Texas through the weekend and will continue to pose a heavy rainfall and flooding threat into early next week. Coastal flooding will likely be an ongoing issue Friday through the weekend as tides will remain elevated. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for life-threatening rainfall flooding having possible extensive impacts across 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. * SURGE: Prepare for life-threatening surge having possible significant impacts across the Upper Texas Coast. Potential impacts in this area include: - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. Also, prepare for locally hazardous surge having possible limited impacts across northern Galveston Bay and Trinity Bay. Elsewhere across Southeast Texas, little to no impact is anticipated. * WIND: Prepare for dangerous wind having possible significant impacts across the Upper Texas Coast, primarily near Matagorda Bay. Potential impacts in this area 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. * 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. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: 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 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 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. $$Tropical Storm Watch
