Ranked by deaths, injuries, damage and size together.
- Tornadoes and Flash Flooding in Texas, October 16 to 17, 2006The combination of very deep tropical moisture with a slow-moving warm front and the approach of a strong upper level trough resulted in excessive rainfall across Harris and various surrounding counties.
- Flash Flooding and Coastal Flood in Texas, October 31, 2015A strong upper level storm system, combined with high moisture levels to produce a bands of excessive rainfall that caused flash flooding across Fort Bend, Harris and Liberty Counties.
- Flash Flooding and Flooding in Texas, March 20 to 28, 2012A slow moving cold front moved to the Texas and Louisiana border through the afternoon and evening of the 20th. Flash floods, floods, and severe weather occurred along and ahead of the creeping boundary.
- Flash Flooding and Coastal Flood in Texas, March 9 to 10, 2016A cut off upper low over West Texas and a stalled frontal boundary over Southeast Texas produced multiple days of very heavy rainfall over the region. Widespread flash flooding occurred across the area with totals ranging from 5 to 20 inches.
- Tropical Storm and Coastal Flood in Texas, June 18 to 21, 2024A Potential Tropical Cyclone became Tropical Storm Alberto as it moved generally westward across the southern Gulf of Mexico and made landfall in the Tampico area. Coastal flooding occurred along the upper Texas coast.
- Coastal Flood in Texas, October 5 to 8, 1996Strong gradient winds produced by a combination of high pressure across the eastern U.S. and Tropical Storm Josephine caused coastal flooding along the Upper Texas Coast.
- Coastal Flood in Texas, November 16 to 17, 1996Tight gradient produce strong east winds that caused coastal flooding and beach errosion along the Upper Texas Coast. Tides ranged between 3-5 feet above predicted astronomical levels. Roads were damaged as well as beachfront homes (foundations undercut).
- Coastal Flood in Texas, April 25 to 27, 1997A strong easterly fetch off the Gulf produced coastal flooding along the upper Texas coast from April 25th-27th. The most extensive flooding/damage occurred from High Island to Jamaica Beach along the Gulf and the western shore of Galveston Bay.
- Flood and Coastal Flood in Texas, April 23, 2023A 500mb shortwave trough worked from northwest to southeast from the Texas Big Bend through Deep South Texas and the Rio Grande Valley, bringing a cold front through the region.
- Tornadoes and Coastal Flood in Texas, May 18 to 21, 2019Another front moved into the region and stalled. Multiple short waves moved across the region while the front was along the coast. Finally on the 21st strong low pressure developed on the boundary and pushed the boundary into the gulf.
- Coastal Flood in Texas, June 7, 2020Elevated swells with long periods from Tropical Storm Cristobal during the early morning hours of the 7th. Tide levels reached 2.5 feet above mean sea level with long period swells running up to the dunes.
- Flash Flooding and Flood in Texas, May 19, 2021A thunderstorm complex moved from the Rio Grande Plains into the Rio Grande Valley during the morning and early afternoon hours on May 19th.
- Coastal Flood in Texas, May 29, 2017After the storms moved offshore into the Gulf of Mexico, strong pressure falls were observed over South Texas, with strong pressure rises noted over the Gulf waters. This produced strong easterly winds across the Coastal Bend and adjacent waters.
- Flash Flooding and Coastal Flood in Texas, November 9 to 10, 2024A frontal boundary moved into the region and stalled while Tropical Storm Rafael meandered in the gulf. Moisture from the decaying tropical cyclone streamed north across Southeast Texas. This produced heavy rain over the area that produced flooding.
- Flash Flooding and Coastal Flood in Texas, December 3, 2016Efficient low level convergence along a near coastal warm frontal boundary within a moist environment generated thunderstorms that produced extreme early day rainfall rates. This intense morning rainfall produced flash flooding.
- Tornadoes and Flash Flooding in Texas, June 19 to 20, 2024Tropical Storm Alberto was a very broad and unorganized storm that developed across the Southwestern Gulf of Mexico. Alberto eventually made landfall between the hours of 4-7 AM on June 20, 2024 near Tampico, Mexico.
- Coastal Flood in Texas, March 1, 2016Large swells of 7 to 8 feet with periods of 10 seconds produced minor coastal flooding at Port Aransas.
- Coastal Flood and Hail in Texas, December 26 to 27, 2018Late evening through early morning severe thunderstorms produced severe hail and some wind damage.
- Tornado and Flash Flooding in Texas, October 24 to 25, 2015The remnants of Hurricane Patricia merged with a developing frontal low to produce an intense surface low off the Texas Gulf Coast.
- Coastal Flood in Texas, October 8 to 13, 2018Persistent onshore flow and high astronomical tides caused periodic flooding of beaches along the middle Texas coast from the 8th until the 11th. Swells from Hurricane Micheal reached the middle Texas coast on the 12th.
- Coastal Flood in Texas, October 8 to 10, 2020Long period swells generated by Hurricane Delta over the northwest Gulf of Mexico impacted the coastal regions of the Middle Texas coast from the evening of October 8th until the morning of October 10th.
- Tropical Storm and Coastal Flood in Texas, July 25 to 26, 2020Hanna made landfall on the lower Texas coast but produced tropical storm force winds and elevated tides, minor coastal flooding across coastal Matagorda and Brazoria Counties.
- Coastal Flood in Texas, October 21 to 23, 2015Persistent onshore flow over several days produced large swells with long periods which impacted the middle Texas coast. Tide levels ranged from 1.5 to 2 feet above the expected levels over the period from October 21st to the 23rd.
- Coastal Flood in Texas, October 6 to 8, 2017A moderate to strong easterly flow persisted across the northern Gulf of Mexico during the first week of October. This flow maintained long period swells that produced elevated tide levels along the Middle Texas Coast.
- Tropical Storm and Coastal Flood in Texas, October 8 to 9, 2020Delta made landfall along the southwest Louisiana coast but produced tropical storm force winds across parts of Southeast Texas. Delta also produced high surf and elevated tides leading to mainly minor coastal flooding along Gulf facing beaches and around Galveston Bay.
