Analyzing The Next Round of Deep Moisture Aimed at California! (credit: Meteorologist Sheldon Kusselson)
DISCUSSION: As discussed above in the guest lecture which was recently delivered by GWCC contributor/consultant and Meteorologist Sheldon Kusselson, here is a neat video lecture covering the incoming moisture advection coming into the state of California! This is certainly a neat watch for any hydrologists, residents living across the state of California, and more. It is worth noting that this is a relatively serious situation based on the recent heavy rainfall which has impacted these drought-stricken parts of California! Be sure to watch the entire discussion above to learn more about this important upcoming flooding threat and more!

DISCUSSION: As of this afternoon the California Department of Water Resources and many county emergency management agencies have issued a mandatory evacuation for Lake Oroville, and surrounding towns. The auxiliary spillway at the Oroville dam has suffered catastrophic damage, as there is a hole in the lower edge of the alternative spillway. This spillway was being used to reduce the levels of water in the lake so any additional water coming into the lake, there would be room to store that water.
The spillway is expected to fail and result in dangerous flooding conditions. The Oroville Dam is the tallest dam in the United States. This immediate information was provided by the California Department of Water Resources. Local law enforcement and agencies are urging residents in Oroville to head north, while in the surrounding Yuba County residents should head South, East and West. As always don’t drive over water covered roads and turn around, don’t drown!

DISCUSSION: As more moisture and energy gradually makes its way across a good portion of the central and eastern Pacific Ocean, there will be a renewed threat for persistent periods of heavy rainfall across a good portion of southern and some parts of central California by next week. The reason for this threat will be an influx of abundant Pacific moisture and jet energy; bolstering the atmospheric dynamics that will help support the larger-scale environment conducive for the generation of heavy rainfall. Moreover, as discussed in the actual Facebook post (courtesy of the National Weather Service office located in San Diego, California), "Long range forecasts are suggesting the return of a rainy pattern in SoCal toward the end of next week, as a dip in the jet stream brings the storm track southward. Current forecasts from the Climate Prediction Center (CPC) suggest a 68% chance for above normal rainfall from February 16th through February 22nd."
