Historic Flood Warning In Sacramento County
Many areas around the country are used to threats of disasters triggered by severe weather. Today, it is our turn. The National Weather Service reported today (10/24/21) that the current weather front moving in, called a bomb cyclone, has the potential to drop the second highest rainfall in Sacramento County history. A bomb cyclone is defined a storm that has the potential to intensify very rapidly. This one has intensified by 24 millibars of pressure in 24 hours. According to the National Weather Service Projections, the current weather system has the potential to drop 4.86 inches of rain over the next 24 hours. By comparison the largest total was 5.28 inches dropped by a rainstorm on April 20th, 1880. If the National Weather Service’s projections are accurate then this storm will give the 1880 storm a run for its money.
As of 8:40PM on Sunday Night the 24th, several areas of Elk Grove are either closed down or are flooded. According to the Elk Grove Police, Northbound Big Horn Boulevard is closed at Hopewell. Civilian reports are also coming in that a field by Grant Line has flooded. Additionally, there is flooding at Mack Road and Center Parkway, as well as the gully behind Laguna Estates near Franklin Rd. and Elk Grove Boulevard, and the field near the overpass at Franklin Boulevard. Elk Grove Tribune will have further updates once the storm is over, presumably Monday.
With last night’s storm finally moving on, we can now accurately measure the total amount of rain that fell on the Sacramento region and it is a new record. Until last night, the record for the total amount of rainfall was from a storm on April 20, 1880 that dropped 5.25 inches of rain. The bomb cyclone that came through last night dropped a record breaking 5.31 inches of rain.
