| Episode narrativeepisode_narrative | Feeder bands from intensifying Hurricane Alex produced a prolonged period of locally heavy rain, gusty winds, and a few tornadoes during the day and evening of June 30th. The center of Alex drifted north-northwest from early evening on the 29th until mid morning of the 30th, reaching a point a little more than 100 miles southeast of Brownsville before accelerating westward into the state of Tamaulipas, Mexico, during the late afternoon and evening. While accelerating, Alex rapidly gained strength as the inner eyewall tightened; at landfall around 8 PM CST on June 30th, Alex had reached 109 mph, just shy of Category 3 (111 mph) strength with a central pressure of 946 mb.||Steady, locally torrential rains added up to roughly 6 to 9 inches for the entire episode across the Lower Rio Grande Valley, and 4 to 6 inches elsewhere. Some locations may have received nearly 10 inches of rain. Three tornadoes were spotted during the morning of June 30th, including two causing notable damage in Cameron County. Sustained tropical storm force winds were limited to Cameron, Willacy, and coastal Kenedy Counties, though gusts to tropical storm force (39 mph or greater) occurred in central and eastern Hidalgo County, covering the more populated Lower Rio Grande Valley. ||Wind damage was minor, at best, outside of locations where tornadoes touched down - and concentrated mainly along and near the coastline. The lack of persistent strong winds minimized power outages, with an estimated 9,000 customers without power across the Rio Grande Valley at the peak of the storm, 8,000 in Cameron County alone. Though property damage was minimal throughout the Lower Rio Grande Valley, nearly $10 million in sorghum grain damage alone was reported in Hidalgo County, a consequence not only of the rainfall but the timing of the rain during a critical growing period.||The heavy rains flooded many poor drainage locations across the Lower Valley, but nowhere near the impact Hurricane Dolly had in 2008, when a band of 12 to 18 inches fell from Laguna Vista through Harlingen toward Raymondville and into eastern Hidalgo County - falling on top of wet soils from previous rains in early July of that year. For Alex, modestly dry conditions through June allowed some of the rains to soak into the ground, reducing the impact of urban and flash flooding during and soon after the event ended.||Significantly worse conditions were noted across the border in Matamoros and Reynosa, Tamaulipas, Mexico. Local rainfall estimates of 10 inches or more combined with poor drainage conditions flooded out six colonias in Matamoros, caused widespread urban type flooding to 400 neighborhoods (80% of the city) and caused significant travel issues. 4,000 residents sought shelter from the floods. In Reynosa, immediately across the border from the City of Hidalgo and Pharr in Hidalgo County, 80 colonias flooded and 15 trees were uprooted, and another seven neighborhoods flooded in nearby Rio Bravo. ||Substantially worse conditions were seen in Monterrey, Nuevo Leon, where torrential rains in the area and along the Sierra Madre Oriental foothills, creating record flows and life-taking flash flooding along the normally dry Santa Catarina River, which set a record flow of 2500 cubic meters per second (cms), or 88,000 cubic feet per second. Estimated rainfall of more than 16 inches fell toward the mountains in a short period of time. Damage was estimated at more than $1.35 billion (USD) as of August 5th.||Incredible rains, perhaps 50 to 70 inches, fell along the east facing slopes of the Sierra Madre in Nuevo Leon and Coahuila State with Alex, and Tropical Depression Number 2 to follow a week later. The one-two punch would ultimately lead to record flooding along the Rio Grande into the Rio Grande Valley for much of July. See the July report for full details. ||For data tables and local summaries, go to http://weather.gov/rgv/?n=2010_alexindex. |
| Event narrativeevent_narrative | Cooperative observers and adjusted radar rainfall estimates suggested between 6 and 8 inches of rain fell across northeast and central Willacy County associated with feeder bands from Hurricane Alex, mostly on June 30th. As of this writing, no significant flash flooding was reported, but heavy rains caused local minor urban-type and field flooding which continued into July 1st. |
