Some of the areas that may see higher rainfall rates already have saturated ground due to rainfall over the past week. This has prompted the National Weather Service to issue flood watches for portions of the Ark-La-Tex Region.


Flood Alerts

Several locations have already seen more than the average rainfall for August in the first 10 days of the month. This includes Tulsa, Oklahoma, with 4.55 inches (August average is 2.9 inches), New Orleans with 6.89 inches (5.98 inches) and Atlanta, where 4.21 inches has fallen (3.9 inches) through Friday.

Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.
