Flooding across San Antonio has turned deadly and led to the cancellation of major Fiesta events on Monday, including the Texas Cavaliers River Parade and Market Square’s Fiesta de los Reyes.
The Market Square celebrations were resumed at noon on Tuesday.
The San Antonio Fire Department says it responded to 24 calls for high water investigations following heavy rain across the city on Monday.
A spokesperson with the department says only one of those calls required actual rescue. Two people were removed from a submerged vehicle.
The other calls were crews responding to assist people from vehicles that had stalled in high water.
One incident resulted in a death when a reported unhoused person was found stranded in a tree in high moving water.
SAFD says no other injuries have been reported.
Organizers explained the Texas Cavaliers River Parade can't be rescheduled before the end of Fiesta this weekend. Logistics are the problem. Around 19,000 folding chairs on the River Walk have already been brought down. And the city needs back a marina, where 57 barges were decorated for the parade, as a part of River Walk operations.
The theme of the parade was "Centennial: Through the Decades."

As of Tuesday, rain chances were very slim for the Battle of Flowers Parade this Friday at 10:30 a.m. and Saturday's 7:45 p.m. Fiesta Flambeau Parade.
Flooding was reported across parts of Bexar, Comal and Guadalupe counties after several inches of rain fell throughout the day. In some areas, totals reached between 3 and 6 inches, with higher amounts in isolated spots.
Rainfall over the past several days has been significant, with totals topping 5 inches in parts of San Antonio. The National Weather Service reports the 4.42 inches of rain that fell at San Antonio International Airport on Monday came close to breaking rainfall for the date of 4.64 inches.
As of Tuesday, year-to-date rainfall at San Antonio International Airport stood at nearly 9 inches or about an inch above the YTD average.
The Edwards Aquifer has risen sharply since the weekend and continues to climb, reflecting how much water the region has absorbed.
Authorities reported multiple road closures across the region due to high water, particularly on low-lying crossings, roads near creeks and in construction zones. Some of the hardest-hit areas were on the northeast side of San Antonio and in communities near New Braunfels and Seguin, where drivers encountered flooded streets overnight and into the Tuesday morning commute.
The National Weather Service issued a flash flood warning Monday evening, later downgrading it to a flood advisory as rainfall began to taper. Minor flooding and hazardous travel conditions remained possible into early Tuesday.
Officials continue to urge drivers to avoid flooded roadways and to turn around when encountering high water. Most flood-related deaths occur in vehicles, and drivers should continue to use caution, especially on roads that may still be covered by water.
Rain is expected to taper through Tuesday night, but at least half the area could still receive another round of rain on Wednesday.
Forecasters say the overall flooding risk would continue to decrease through Tuesday, though some roads may remain closed and isolated high water could persist, especially in low-lying areas.
A warming trend is expected midweek, with highs returning to the 80s by Wednesday and climbing into the upper 80s by Friday. While widespread rain is not expected, isolated storms remain possible later in the week and into the weekend.
Organizers have also canceled or postponed additional Fiesta events scheduled for Tuesday. Eva’s Heroes “Ain’t Gonna Resta ’Til After Fiesta” Dance has been postponed, and disABILITYsa’s Celebration Day has been canceled due to weather concerns.
