What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Brownsville, TX wrote its last area forecast discussion before this flash flood watch went out at Jul 24, 6:39 AM CDT, 2 hours 31 minutes earlier.
Area forecast discussion, Jul 24, 6:39 AM CDT, 2 hours 31 minutes before
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 639 AM CDT Fri Jul 24 2020 .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...Satellite imagery shows mostly high clouds passing over the Rio Grande Valley early this morning. VFR conditions are expected to continue until about midday today when showers and thunderstorms form along the sea breeze and bring intermittent MVFR conditions this afternoon. Rain chances will increase through the period as Tropical Storm Hanna nears the lower Texas coast. Winds will start off from the north and gradually shift easterly and then southerly tonight, but will generally remain light through the period, except for any locally moderate gusts in shower or thunderstorm activity. && .PREV DISCUSSION... /issued 504 AM CDT Fri Jul 24 2020/ ..TROPICAL STORM HANNA MOVING WEST TOWARD SATURDAY LANDFALL NEAR BAFFIN BAY... ..TROPICAL STORM WARNINGS IN EFFECT... SHORT TERM (Now through Saturday): The main concern for the short term period continues to be the potential impacts from Tropical Storm Hanna (upgraded overnight from Tropical Depression 8). As of 10 PM CDT on Thursday, TS Hanna was located in the northwestern Gulf near latitude 26.2 North, longitude 91.4 West and is expected to move toward the west-northwest and make landfall somewhere along the South Texas coast midday Saturday with a maximum intensity around 55 knots or just over 60 mph. The forecasted track of Hanna has trended southward over the last couple of NHC advisory packages, matching the recent model trends, and effectively increasing the potential impacts across Deep South Texas. The main impact continues to be heavy rain and flash flooding as this slow moving system brings ample tropical moisture to our area. Precipitable water values near 2.7 inches on Saturday, putting expected peak rainfall amounts around 4 to 8 inches, with isolated amounts up to 12 inches possible. With the expected rainfall, the Weather Prediction Center has included the coastal areas in a marginal risk for excessive rainfall today, and a slight and moderate risk for excessive rainfall on Saturday when we're expecting Hanna to move inland. Tropical-Storm-force winds are also expected to impact most of Deep South Texas where Tropical Storm Warnings are in effect as the system moves inland on Saturday. Follow the latest updates from the National Hurricane Center as adjustments to the track are made. Have held off on issuing a Flash Flood Watch in this forecast package after collaborating with our neighboring NWS office, but one will likely be issued during the next package as confidence increases. Swell across the coastal waters from Tropical Storm Hanna may produce minor coastal flooding beginning late this afternoon, with water rising up to or near the dunes, especially on narrow beaches. Current water levels at SPI Brazos Santiago continue to show levels about a foot above predicted tides. Thus, a Coastal Flood Advisory may be needed later today. Otherwise, temperatures are expected to be near seasonal normal today with light northerly winds shifting northeasterly this afternoon. Rain chances will increase across the Gulf waters and our eastern counties today as distant bands from TS Hanna along with any sea breeze initiation move westward across our area. As can be expected, temperatures will be significantly cooler on Saturday with the widespread shower and thunderstorm activity. LONG TERM (Saturday Night through Thursday): With Hanna making landfall along the northern portion of the lower Texas Coast on Saturday, concerns have increased for areas of heavy rainfall and flash flooding. These concerns will heighten on Saturday, but will also continue into Saturday night. Two to four inches of rain will be possible Saturday night, adding on to any rain received earlier. No flash flood watches have yet been posted, as comparisons with flash flood guidance continue, but the potential remains. In addition, in the area where Hanna makes landfall, strong winds of 35 to 45 mph with gusts to 55 mph will be possible. After making landfall, Hanna will turn west southwest and curve across the northern tier of deep South Texas before crossing the Rio Grande into Northeast Mexico. Hanna will weaken quickly after she makes landfall, however, with Saturday night being the worst period of the long term, and with improving conditions on Sunday. Elevated shower and thunderstorm chances will remain in the area through the weekend and into early next week, however the heavy rainfall threat should taper off after Sunday for eastern sections, though lingering for western sections into Monday. Conditions will remain unsettled for much of the remainder of the long term in the aftermath of Hanna. A weakness will remain in the mid levels with ample tropical moisture persisting into the middle of the week. High temperatures will be held down to around 90 to 95 for most areas, but ample moisture will help maintain elevated heat index values to 100 degrees or higher. Temperatures and heat index values will trend slowly higher during the week. MARINE: Now through Saturday: With a weak pressure gradient in place, winds will remain light through this evening, but seas will increase overnight as swell from Tropical Storm Hanna reaches the lower Texas coastal waters. A Tropical Storm Warning is currently in effect over all of the lower Texas coastal waters, with winds and seas expected to rapidly deteriorate late tonight into Saturday. In addition, showers and thunderstorms will increase through the period, which will add to the hazardous conditions. Follow the latest updates on Tropical Storm Hanna from the National Hurricane Center. Saturday Night through Tuesday...Tropical storm conditions may still be ongoing Saturday night. High seas will be developed across the northern marine areas. However, as Hanna continues farther west and moves inland, conditions will rapidly improve. Small craft should exercise conditions will be possible on Sunday, with light to moderate southeast winds and low to moderate seas on Monday and Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
