A 541 dm upper-level trough of low-pressure along the California coastline will direct a series of surface lows and frontal systems into the Central Coast starting Sunday evening into Thursday. These vigorous surface lows, fronts and troughs will produce periods of moderate gale-force to fresh gale-force (32 to 46 mph with gust 55 mph) southerly winds along our coastline and heavy rain throughout the Central Coast, especially along the southerly facing slopes.

Both the ECMWF & GFS model runs have increased cumulative rainfall totals. If these models verify, between 3 and 7 inches of rain is forecast this evening through Thursday with Big Sur receiving as much as 10 inches of rain over this period. The strongest winds and heaviest rain is expected on Thursday. Please see https://twitter.com/pge_john for rainfall graphics. Dry conditions return over the Martin Luther King holiday weekend with generally above average daily temperatures.

A prolonged period of moderate gale-force to fresh gale- force (32 to 46 mph with gust 55 mph) southerly winds are forecast along our coastline starting Sunday evening and continuing through Thursday. These winds will generate 6- to 8-foot (180-degree, shallow-water) seas Sunday night into Tuesday morning, increasing to 9 to 11 feet on Tuesday afternoon and night. These southerly seas will decrease to 6 to 8 feet on Wednesday into Thursday afternoon.

Combined with these southerly seas will be an 8- to 10-foot northwesterly (295-degree, deep-water) swell, with a 22- to 27-second period, on Sunday, increasing to 11 to 13 feet, with an 18- to 20-second period, on Monday into Tuesday. A 9- to 11-foot northwesterly (295-degree, deep-water) swell, with a 15- to 19-second period, is forecast along our coastline on Wednesday.
