The return of showers and thunderstorms today is the last thing residents of San Antonio want to hear in the wake of Saturday's deadly flooding.
The good news is that a repeat of Saturday's inundation that dropped more than 9 inches of rain in less than seven hours is not expected.
Today's showers and thunderstorms will be spottier in nature and should not sit stubbornly over San Antonio as long as Saturday's rain did. However, residents should not let their guard down.
Any showers and thunderstorms crossing San Antonio could produce downpours that will have no trouble triggering new flooding problems with the ground severely saturated and streams/rivers still swollen.
Low-lying and poor drainage areas are most susceptible to renewed or worsening flooding problems today. Those along streams and rivers should prepare for possible rapid rises.
Today's showers and thunderstorms follow the torrential rain that made May 25 San Antonio's second wettest day on record and triggered the severe flooding that claimed two lives.
The combination of a weak and slow-moving upper-level disturbance and moisture from the Gulf of Mexico led to the inundation. Before Saturday's rain, the ground was also already saturated by the 2.33 inches that fell on Friday.
A total of 9.87 inches of rain poured down on Saturday, all before noon CDT, falling second to October 17, 1998, and its 11.26 inches as the city's all-time wettest day.
San Antonio averages 4.01 inches of rain each May and 32.27 inches during an entire year.
Saturday's rain came down so quickly that the level of the San Antonio River at Loop 410 soared from 4.54 feet to a record 34.21 feet in less than four hours.
Levels of streams and rivers throughout the San Antonio area were residing this morning, but that course threatens to be reversed by any significant downpour as today progresses.
Drier weather should finally grace the city for Memorial Day.
