That's exactly what happened in Rockdale before dawn Sunday as the end of an 11-inch, four-day deluge closed streets and turned driving into an adventure.
There was a high-water rescue at the Texas 36 underpass in Milano and many farm-market roads in the northwestern part of Milam County were closed over the weekend.
Rainfall actually began Friday with a total just over a half-inch. but Rockdale didn't get the brunt of a highly unstable air mass until Saturday night when a line of thunderstorms stalled over Milam County.
Virtually all of the 7.7 inches recorded on Sunday fell before sunrise.
By dawn Sunday the U.S. Weather Service rain gauge at KRXT-FM recorded a four-day total of 11.2 inches.
That's almost as much rain in four days as had fallen in the first eight months and eight days of 2009 combined.
About 4 a.m. Sunday what had been a steady rain turned into a deluge, flooding low-lying areas in Central and East Rockdale.
The often-flooded intersection of US 79 (Cameron Avenue) and Meadow was closed as were portions of Ackerman, San Gabriel, Bell and Charles streets.
A portion of US 79 near Rice Street was also brief ly closed and the flood gate on the Belton Avenue low-water crossing was shut.
The Milano Volunteer Fire Department extricated a driver from the flooded Texas 36 underpass after her vehicle stalled in high water.
According to the MVFD, the driver handled the situation correctly, calling 911 on her cell phone immediately and remaining in the vehicle until help arrived.
That highway was briefly closed by the high water at the underpass.
FM 1915 in northern Milam County was closed at Big Elm Creek and FM 486 at the Little River. There were reports of the Little River being out of its banks under the long bridge near Cameron.
County roads closed at some time during the weekend included CRs 119, 120, 147, 203, 230, 335, 402, 405, 408, 408, 412 and 414.
The sheer amount of the weekend's rain was unexpected.
The 11.2-inch total makes September, 2009, already the fifth wettest month of the past 20 years.
Only wetter months in that period were:
May, 2000, 16.83 inches; July, 2007, 15.01; October, 1994, 11.73; June, 2004, 11.61.
