Numerous trees and power poles were knocked down. In Ramona entire barns were destroyed.
1977: "Once in a lifetime" wind and dust storm struck the south end of the Valley.
Winds reached 88 mph at Arvin before the anemometer broke and gusts were estimated at 192 mph at Arvin by a US Geological Survey.
Meadows Field in Bakersfield recorded sustained 46 mph winds with a gust of 63 mph.
The strong winds generated a wall of dust resembling a tidal wave that was 5,000 feet high over Arvin.
Blowing sand stripped painted surfaces to bare metal and trapped people in vehicles for several hours.
Seventy percent of homes received structural damage in Arvin, Edison and East Bakersfield. 120,000 Kern County customers lost power.
