Flown by the U.S. Geological Survey between 1937 and 1989, the Aerial Photo Single Frames collection is the definitive mid-century view of the land: fields, roads and rivers as the camera saw them. The Survey holds 3,676 frames inside the rectangle that bounds this county; the 40 frames below were taken over the county itself, chosen across the decades of flights (at most four a year from that rectangle), so one flight cannot crowd out the rest. The full set is free to browse and download at EarthExplorer under the dataset Aerial Photo Single Frames.

| July 2010 | Flood | Zapata Arpt | $1,000,000 | Incredible rainfall estimated to be more than 50 inches in around 10 days' time between June 30th and July 9th across the front range and peaks of the Sierra Madre Oriental in Coahuila Province, Mexico, ultimately flowed through the entire Lower Rio Grande basin for much of the summer of 2010. The rare and extreme event ultimately led to increasing water levels at both Amistad International Reservoir (northwest of Del Rio, TX) and Falcon International Reservoir (adjacent to Zapata County), the result of inflow from Mexican tributaries and upstream reservoirs along the Rio Salado and Rio Conchos in Nuevo Leon and Coahuila State, Mexico. ||At Falcon International Reservoir, where inflow from both the upstream Mexican tributaries and Amistad International Reservoir, which had begun releases of 35,000 cubic feet per second (cfs) on July 5th, the pool level rose above conservation stage (301.2 feet) during the morning of July 12th, and would continue a steady rise, reaching moderate flood stage (306.7 feet, the point where impacts begin along the shoreline) during the pre-dawn hours of July 14th. Despite an increase in releases from 39,700 cfs to 60,000 cfs from the Reservoir, the pool level continued to rise, peaking at a new record stage of 309.31 feet during the evening of July 17th. The continued high pool level required maintaining releases of 60,000 cubic feet per second for nearly 14 consecutive days, in order to maintain a manageable water level at the dam. At Falcon, the previous record of 308.1 feet (set in October, 1958) was not only broken, but the pool level remained above the prior record for nearly 7 full days, from around 130 AM CDT on July 15th through 930 PM on July 22nd. The pool level was above conservation level (301.2 feet) from the morning of July 12th through 4 PM on August 13th, more than a month. ||Releases were gradually lowered toward the end of the month as the pool level began to fall more steadily heading into early August.||During the period of time when the reservoir was in moderate flood, or above 306.7 feet, structures and infrastructure was impacted along the shoreline. At least 33 homes had some level of water incursion; damages were still being assessed as of this writing. Lakefront roads were under some water for weeks as well. Individual damage reports included an estimated $35.5 thousand to water pumps and related equipment. Business losses also mounted at the Reservoir, where bass fishing is popular. At least $15.3 thousand in losses was reported at Falcon State Park. ||As of late September, a best estimate for property and infrastructure damage in Zapata County was at least $1 million; more is likely when the assessments are completed in autumn 2010. |
| May 2008 | Thunderstorm Wind | Zapata Arpt | $750,000 | Damage from the microburst was first surveyed about 2 miles west of the center of town along and near Farm to Market (FM) Highway 496. In the neighborhood of Falcon Mesa, along FM 3074, numerous barrel tiles were torn from the roof; in the same neighborhood, numerous large limbs from ebony and live oak trees were blown down, and minor damage to roofs was noted at other homes. Similar tree and roof damage was noted at another neighborhood along Oak Street, just south of the Zapata Cemetary.||Farther east along FM 496, several large fiberglass storage tanks were rolled, and damaged beyond repair, at a facility between FM 3074 and the Zapata County cemetary. On the same property, a manufactured home had numerous holes in its west facing wall, from wind driven pebbles and stones. The same home had fairly significant asphalt shingle damage to its roof. A nearby low metal tower was bent in half.||The worst-looking damage was seen just west of the center of town, along FM 496 only 1/3 mile west of the intersection of Federal Highway 83. Here, significant damage was incurred to many units at the Highway 496 Storage facility. ||The microburst slammed into the west facing wall of the first of two long, cinderblock structures, and lifted most of the roof up and over the first building, slamming it into the second building about 50 feet to the east. While the truss and bracing of the roof appeared sound, only long nails were found at the connections of the eaves. Missiles generated by the broken roof drove into both cinderblock, and an individual metal garage, in the second building. Another light metal structure, housing another set of individual storage units, separated and collapsed on the leeward side of the second building. ||The microburst continued moving steadily southeast, causing notable damage to neighborhoods in the southwest part of town. Dozens of homes and other structures with poorly anchored roofing material sustained significant damage; a large portion of tin roof was removed from a two story church a few blocks from the center of town. Another barrel-tile roof was damaged at a motel, and the water leak caused at least one unit to be uninhabitable.||In all neighborhoods, hundreds of mesquite and ebony tree limbs of many shapes and sizes were snapped off, some onto roofs, including the town's public library. As the storm finally edged south, additional tree damage was noted in the Falcon Lake Estates subdivision, just south of the bridge, where a report of a blown down roof of a two story house was also received as the storm weakened slightly.||The Zapata County Emergency Manager reported power lines and several trees were down in Zapata and approximately 200 to 300 people were without power at 9 pm. ||Wind speeds were estimated to be between 70 and 75 mph area wide, with the strongest speeds generally along and just south of FM 496 from just west of the cemetary to highway 83. Total path length was estimated to be a little more than 3.5 miles long; width was estimated to be about 1.5 miles. |
| April 1993 | Hail | Zapata | $500,000 | Hail up baseball-size was reported in Zapata. Over 200 claims have been filed for damage to homes and cars. The hail penetrated metal awnings and damaged cactus plants in the area. |
| May 2022 | Flash Flood | Zapata | $300,000 | Video on social media shows several feet of fast moving water near Medina Street - a flood-prone area known as Medina Addition - with two SUVs that had been swept off the road and into a ditch. Video later shows the vehicles getting dragged out of the ditch by a tow truck. Based on the during and after videos, it is estimated that 3 to 4 feet of fast flowing water was moving across the road at the height of the flash flooding. Additional video shows people having to abandon homes during the height of the flooding and the water coming up to their waists, which supports the 3 to 4 foot estimates of fast moving water. A report of 8 of rain came in from just northwest of Zapata from this storm. The local newspaper in Zapata County later reported that at least 15 homes were affected with many of them losing their furniture, clothing, and household items. |
| May 2020 | Thunderstorm Wind | Zapata Arpt | $250,000 | A rapidly developing severe thunderstorm crossed the Rio Grande into Zapata County shortly after midnight on May 26. The storm produced damaging straight line winds across much of the city of Zapata, including portions of Medina Addition to the east and Sierra Shores to the south. Widespread damage was surveyed across the city with more than two dozen single wide mobile and manufactured homes having partial or total roof damage. Nearly all of the critically damaged infrastructure was of poor and older construction. More than a dozen wooden utility poles were leaning or broken, most of which had wet or rotting bases. Hundreds of healthy large tree branches were blown down, in addition to dozens of uprooted trees with shallow root systems. |

Winds at nearby Zapata County Airport (Medina) were clocked at 44 mph 5 minutes earlier. Construction type and damage, combined with no nearby reports of more traditional damage (large limbs, roof material, etc.) suggested a pulse gust below 58 mph. |
| April 2009 | Hail | Zapata | $2,000 | Hail fell for more than 15 minutes near Zapata County during the mid evening. The Zapata County Emergency Management Coordinator received a report of quarter size hail in the Las Palmas subdivision, about 4 miles northeast of the City of Zapata.

The Zapata County Sheriffs Office reported minor flooding along Federal Highway 83 in the San Ygnacio area north of the City of Zapata toward the Webb County line. The flooding was reported between Corralitos and the La Perla Ranch, Lake #4, area. ||The Manager of the Zapata County Airport recorded 3.75 inches of rain, in addition to the fairly long duration of quarter size hail. Radar rainfall estimates were over 7 inches, but likely contaminated by the prodigious hail. Still, it is conceivable that more than 4 inches fell in a few spots, leading to enough water flowing across roads to consider the event a Flash Flood. |
| August 2008 | Flash Flood | San Ygnacio | $1,000 | Water and mud was covering portions of US Highway 83 near and north of San Ygnacio as a result of thunderstorms which produced heavy rainfall in the area during the afternoon. Water was also flowing across the highway during this time, as well. |
