Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A ridge of high pressure will build over the West Coast, producing moderate to fresh (13 to 24 mph) and at times gusty Santa Lucia (northeasterly) winds, higher temperatures and mostly clear skies in the coastal regions starting Monday and continuing through Thursday afternoon.
High temperatures could reach the low 70s throughout the Central coast starting Tuesday and continuing through Thursday.
However, conditions will be favorable for night and morning dense ground fog across the North County — and especially in the San Joaquin Valley, where fog could persist into the early afternoon each day.
Never miss a local story.
Marine low clouds with areas of mist and drizzle are forecast to develop along our coastline Thursday night into Friday.
Current longer-range forecast models suggest a stormy weather pattern starting Saturday and continuing through the following week.
The models are indicating a particularly strong low-pressure system developing off the California Coast on Sunday with moderate gale-force to fresh gale-force (32 to 46 mph) southeasterly winds, heavy rain and high seas. These are long-range models; consequently, the timing and intensity of this predicted storm will probably change as the week progresses.
Sunday morning’s 8- to 10-foot northwesterly (295 degree, deep water) swell (with an 11- to 13-second period) will decrease to 4 to 6 feet with the same period Monday.
A 5- to 7-foot west-northwesterly (285 degree, deep water) swell (with an 18- to 20-second period) is forecast Tuesday, increasing to 8 to 10 feet (with a 15- to 17-second period) Wednesday into Thursday afternoon.
An intense storm with hurricane-force winds developed near the international date line and will travel westward. An 8- to 10-foot west-northwesterly (285 degree, deep water) swell (with a 20- to 22-second period) from this storm will arrive Thursday night, building to 11 to 13 feet (with an 18- to 20-second period) Friday and decreasing Saturday.
The longer-range models are advertising a 15- to 17-foot west-southwesterly sea and swell (with a 5- to 15-second period) next Sunday and Monday. Another high-energy wave event is expected Feb. 3.
Seawater temperatures will range between 56 and 58 degrees through next Monday.
