Overnight Storm Brings Flooding Rains and Spectacular LightningJuly 15th, 2012 at 11:00 am by davidyeomans under Weather
A brief overnight flare-up of showers and thunderstorms over central Texas brought flooding rains and an incredible lightning show to Williamson and Travis counties.
The storms came and went fairly quickly – firing around 11pm and dissipating around 1am – but still managed to leave their mark in a big way. A Flash Flood Warning was issued for parts of Williamson and Travis counties, citing heavy rain rates and street flooding. Spicewood Springs Rd. between Old Lampasas Trail and Loop 360 was closed for a period of time early this morning due to flooding.
Eastern parts of the city were spared from the storm, as ABIA only received 0.01″ of rain overnight. Camp Mabry, however, got an impressive 1.28″. An LCRA rain gauge at Bull Creek & Loop 360 was the night’s winner, with a storm total of 2.10″! A snippet of the rainfall record from this LCRA gauge can be seen below (and also on LCRA’s Hydromet page).

Rainfall is recorded every 15 minutes on these automated gauges. The 0.70″ rain total between 12:10am and 12:25am calculates out to a rain rate of 2.8 inches per hour! This was an extremely heavy downpour.
The rapidly-intensifying storms also produced a spectacular lightning show for all of Austin to see. If you have any photos of the lightning last night, please send them to firstname.lastname@example.org or use the Report It button on our free KXAN smartphone app. Have a great Sunday!
