Worse than Dolly? Widespread Flooding Eviscerates Drought; Impacts Entire Rio Grande Valley June 18-22, 2018

A broad tropical wave originating in the western Caribbean Sea moved across the Yucatan peninsula on June 15th and 16th, 2018. The slow moving but persistent system approached the Texas coast on Sunday, June 17th before finally arriving on June 18th. As the center axis of the wave passed the longitude of the coastline, the gates opened to repeated surges of tropical moisture deep into the atmosphere with origins in the western Caribbean Sea. A series of upper level disturbances interacted with this wave throughout its life cycle and helped to maintain a broad area of low pressure at all levels of the atmosphere for the period from June 18th through June 22nd across Rio Grande Valley, and the adjacent Gulf waters. Several surface-based boundaries and convergence along the coastline also aided the production of heavy rainfall. Individual convective "systems" spun in place at several points during the event, including:

  • Tuesday morning (June 19) in Brooks County
  • Tuesday afternoon over Cameron County
  • Early Wednesday (June 20) in Hidalgo, Cameron, and Willacy County
  • Wednesday afternoon again in Cameron and Willacy County
  • Thursday morning (June 21) in Starr and Hidalgo County
  • Thursday afternoon in Cameron, Willacy, and Kenedy County
  • And finally, Friday morning (June 22) in southwest Hidalgo and southern Starr County along the Rio Grande.

The wave and upper level disturbances finally exited southwest into north central Mexico on June 22nd, bringing a weekend of rain-free but oppressively hot and humid conditions to conduct broad recovery activity across the region.

 

Bout after Bout after Bout Ends the Drought but Wreaks Memorable Havoc

A wise Texas meteorologist from the early 20th Century aptly stated: "Texas is a State of perpetual drought, broken by the occasional [devastating] flood". How right he was, nearly 100 years later. Severe-level drought, which had turned grass and rangeland crispy and yellow-brown and burned up non-irrigated crops by mid June, was replaced in days with scenes of several feet of water that flooded thousands of vehicles, inundated several thousand homes and businesses with 18 inches to more than 3 feet of water, and hundreds of rescues of persons and pets. As of June 25, state Emergency Declarations were declared for Cameron, Hidalgo, and Willacy County. Damage estimates were likely to run into the hundreds of millions of dollars, and the breadth of impact was perhaps even greater than that of Hurricane Dolly in 2008.

The first bout of heavy rain was more welcome than anything else: A pre-dawn roaring downpour that dropped 2 to more than 3 inches between Los Fresnos and Harlingen on June 18th. The morning rain, which spared many other locations, was a teaser of much more to come. The first serious flooding event developed during the late night and early morning hours of June 19th across the South Texas Brush Country of Duval, Jim Wells, and Brooks County. Torrential rains of more than 12 inches by midday west of Falfurrias, and flooding of at least 1 to 2 feet of water covered the streets of the city, closing many of them. Soon after, Palo Blanco Creek overspilled its banks and contributed additional water flows, and Los Olmos Creek spiked quickly and by evening reached flood stage by late afternoon and would crest just over moderate stage (12.32 feet) around 745 PM June 19th - the third highest crest in the modern record and highest since 1971 (remnants of Hurricane Fern).

The second flooding rain event struck Cameron County from Brownsville to Los Fresnos, when a slow moving line of thunderstorms from west to east intersected the sea breeze and stalled, dumping 3 to 5 inches of rain over a 2 to 3 hour period and caused significant street flooding and some road closures in the area. The "big one" followed just 12 hours later, when the peak of the tropical moisture plume was lifted by an embedded upper level disturbance parked between the central Rio Grande Valley and the South Texas Brush Country. Incredible rainfall rates of up to 5 or more inches per hour struck the highly populated mid Valley between the east side of the McAllen Metro region to Harlingen, with peak rainfall just north of Weslaco and Mercedes. 11 to 13 inches fell in just a few hours at and near the Mid Valley Airport in Weslaco, though amounts may have been a couple inches higher in the heaviest rain core several miles northeast of this location. Drainage was unable to handle the deluge, and widespread flooding with photo and video evidence of at least 3 to 5 feet of water depth in many streets of each town ensued. The number of homes, businesses, and vehicles impacted by the floodwaters exceeded that from the October 22-24 Atmospheric River Event. As of this writing, Weslaco City estimates were more than 2500 homes, 100+ businesses, and at least 2500 vehicles with various degrees of damage. The homes and businesses had a minimum of 18 inches of floodwater depth inside portions of each. Data from Mercedes had not been received as of June 26th.

The third event struck Cameron County - again - in nearly the same locations between Brownsville and northeast of Los Fresnos that same afternoon. This time, 4 to 6 inches fell, making for two day totals of 6 to 10 inches in the area and triggering additional flooding, especially in and northeast of Los Fresnos where several neighborhoods were inundated by a foot or more of water, with estimates of 3 feet or more of standing water in poor drainage locations as well as open fields. Parts of Harlingen were dealt a "triple" blow with rain during the afternoon of the 19th, morning of the 20th, and afternoon of the 20th. 10 inches fell there as well.

By evening of the 20th, a defined swirl of upper level energy - in part due to the interaction of the earlier thunderstorm system with the broader tropical wave - settled over the four corners of Brooks/Hidalgo/Starr/Jim Hogg County. The system would drift little overnight; another complex of thunderstorms would spin in from the northeast overnight and reach Starr County, eventually dropping more than 7 inches from the ranches north of Rio Grande City to Rio Grande City itself, where local arroyos reached and overtopped their banks and at least one swift water rescue was required during the pre-dawn hours of the 21st. The big story of that day was just beginning, however, as a "fire hose" of moisture on the immediate east side of the swirl was lifted into a persistent band of torrential rains that began in western Hidalgo County before daybreak, where estimates of 6 to 8 inches fell, to the McAllen metro area between 7 AM and Noon, where estimates of another 6 to 10 inches fell, based on radar and ground truth observations. At least 2700 residences and businesses were estimated to be flooded in many neighborhoods in Mission and McAllen, as the additional rain fell on previously saturated ground from 3 to 6 inches that fell during the pre-dawn hours of June 20th.

For Cameron County, one more act was to come, as multiple shorter-lived bands of torrential rains rolled through Brownsville to Los Fresnos (again!) dropping another 1 to nearly 3 inches from late morning through mid afternoon of the 21st, which aggravated ongoing high water and flood conditions as well as recovery operations. The final act of the entire event occurred during the pre-dawn hours of June 22nd, when a final cluster rotated from the central Tamaulipas coast to the Mission/McAllen area as the tropical wave wheezed to its demise while moving southwestward into north central Mexico. An additional inch or two of rain aggravated ongoing flooding in these areas, as well as in Starr County near the Rio Grande.

Rainfall totals are listed in Rainfall tab of this report. In general, between 12 and more than 18 inches fell in the McAllen/Mission area, up to 16 inches fell near Weslaco, with the potential of 18 inches between Weslaco and Mercedes; 8 to 17 inches in Harlingen; 10 to 15 inches between Brownsville and Los Fresnos, 10 to 15+ inches in Port Mansfield and through the King Ranch of Kenedy County, 12 inches near Falfurrias, and more than 8 inches in parts of Starr County.

In addition to arroyos, drainage canals and ditches, resacas, and arroyos that filled to the brim and in some cases overspilled, gaged creeks and a portion of the Rio Grande also swelled to flood levels. The following crests were noted at three locations across the Rio Grande Valley and Deep South Texas:

  • Los Olmos Creek near Falfurrias crested at 12.32 feet (moderate flood condition) during the evening of June 19th. This was the highest level observed since 1971, when Tropical Cyclone Fern dropped more than 10 inches of rainfall in a short period of time across the South Texas Brush Country.
  • The Arroyo Colorado crested at 23.98 feet, the highest level since the Hurricane Alex Flood Control System (Floodway) event. This time, there was no release of water along the Rio Grande basin (i.e. from Falcon International Reservoir), just runoff from the rainfall listed above.
  • The Rio Grande near San Benito crested at 51.6 feet, the highest since the Flood Control System event of July 2010.

Tale of the Tape - Initial Impact Statistics

The Great June 2018 Flood of the Rio Grande Valley will be remembered for a long time to come, not just for its damage which is likely to run at least $250 million, with the potential for $500 million or more - but also for the challenges faced by the region for potentially much more rainfall from an organized tropical cyclone that decides to sit and spin over the region for a few days - perhaps worse than Beulah, but in a region with five times the population and exponential infrastructure growth. The following information is from initial reports from Emergency Management partners across the Rio Grande Valley. This summary will be updated as additional information is received.

  • More than 7,400 residences and businesses in Cameron and Willacy County with flood damage defined as minor to destructive by FEMA Standards.
  • At least 20,000 residences and businesses considered "affected" by the floods. This includes the 7,400 listed above.
  • More than 600 persons in at least ten shelters at the peak of the area-wide flooding
  • Several thousand vehicles with varying degrees of flood damage
  • Dozens to hundreds of roads, from neighborhood streets to major thoroughfares and frontage roads, closed during and after peak flooding
  • More than 2,000 rescues from vehicles and homes were conducted
  • 21,000 meals served by the American Red Cross
  • Public infrastructure damage of at least $50 million in Cameron and Willacy County alone

So far, we've heard of no direct injuries or deaths from the flood despite the widespread damage, a testament to the resiliency of residents and families of the Rio Grande Valley and the public safety officials and workers who are critical to our shared mission to protect life and property.
