More rain is in the forecast for the Highland Lakes from Oct. 27-30, which will be followed by cold temperatures, including a low of 35 degrees on Halloween night. The National Weather Service warned of flood risks through the weekend following the recent storms that caused huge surges in waterways across Llano and Burnet counties.
Heavy rainfall is possible Friday evening, but the biggest showers could come on Monday, Oct. 30, accompanied by a cold front. Monday’s expected high is only 45 degrees; the low 39 degrees. The colder weather will continue throughout the week with highs in the 50s and low 60s with partly sunny to sunny skies and lows dipping into the 30s.
The Llano and Colorado rivers are still running high after torrential rainfall across their watersheds caused massive flow rates that haven’t been seen since the flooding of October 2018. The Llano River crested at over 32,000 cubic-feet per second on Thursday; the Colorado River at 6,600 cfs the same day. As of 2 p.m. Friday, the Llano River was rushing at over 7,700 cfs; the Colorado River at over 2,400 cfs.
With the rivers still high, heavy rains could contribute to more severe flooding and road closures across Llano and Burnet counties.
