NOT GOOD: San Antonio’s in its driest stretch since 1996 ahead of a dry La Niña winter forecast

KEY POINTS

  • Drought continues to quickly worsen across South Central Texas
  • September & October are typically San Antonio’s rainy season, but it’s been more than 45 days since San Antonio recorded any measurable rainfall

DROUGHT WORSENS

It’s no secret that we need rain.

On average, September and October bring healthy rains to San Antonio. So far, it has been anything but that.

After a great start to the month of September with 1.46 inches in the official rain gauge, San Antonio has yet to record any measurable rainfall at the San Antonio International Airport since Sept. 5… that was more than 45 days ago. That makes this recent consecutive dry stretch the longest since 1996! The longest on record? 63 days from June 27 to August 28, 1993.

The lack of rain and warmer-than-average temperatures stretching well into October have been major contributors to this rapidly intensifying drought.

The latest drought monitor (pictured below) shows these changes:

  • Moderate drought (tan) now encompasses our far eastern counties and much of the Coastal Plains
  • Severe drought (orange) has now expanded south and east of I-35
  • Extreme drought (red) is now in place across northwestern Bexar County and additional parts of the Hill Country

ACROSS THE STATE

On a statewide scale, more than half of Texas is considered to be in a drought. The worst of the drought is currently positioned across far West Texas in the Big Bend region.


LOW WATER LEVELS

The Edwards Aquifer, lakes, reservoirs, and rivers home to South Central Texas continue to feel the effects of this prolonged drought and lack of rainfall. Here’s a look at some of the latest levels:

Area lakes and reservoirs continue to feel the impacts of long-term drought.

LOOKING AHEAD: La Niña

Only minimal (10%-20%) rain chances are in the forecast over the next 10 days, with nothing of major significance to note.

The latest outlook issued by the Climate Prediction Center is still calling for a drier-than-average November, followed by more of the same into the upcoming winter season.

Speaking of winter: In the outlook issued by the National Oceanic and Atmospheric Administration (NOAA), forecasters expect La Niña conditions to develop later this year. This would likely mean a drier and warmer than average winter season for South Central Texas.

This doesn’t mean that we won’t see rain events or a few cold snaps (because we will), but on average, a La Niña pattern typically means drier and warmer conditions for South Central Texas in the winter.

Overall, it is not a good outlook considering our current drought situation. Still, we’ll keep you posted.
