Texas Size Flooding

While the headlines have been about the flooding across Louisiana the past week or so, that storm system has finally left the region.  However, we are dealing with persistent thunderstorm activity over the Lonestar state of Texas.

Rivers in the area are starting to rise, and some, have shot up drastically, within a short period of time.  The Cibolo Creek near Falls City, TX had a rise of roughly 26 feet in 17 hours.  That is a roughly 1.5 foot rise per hour.  Flood stage for that point in the creek is 17 feet and so it is in a major flood stage.

The San Antonio River at Elmendorf, TX rose from 13 feet to nearly 39 feet over 22 hours.  That is a rise of 1.19 feet per minute.  That river is in a moderate flood stage but is forecast to go down over the next few days below flood stage of 35 feet.

Over the next few days, we’ll see a few more inches coming in, but some spots could see at least 4 inches.

The extended forecast for Austin and San Antonio show a few chances for rain to come by, even some thunderstorms, but we’ll also see some chances to dry out, with some sunshine.

  1. I remember a time back in the forty’s where it rained almost every other day and there were peach trees with tons of fruit. Gone today replaced by drought desert and mesquite trees. Now it seems San Antonio gets all it’s precipitation all at one time or in big trash moving rains.
