SEA/SWELL:

The westerly swell at the Diablo Canyon waverider buoy
peaked at 17.2 feet with an 18-second period at 3 p.m.
on Thursday. The Santa Lucia Escarpment waverider buoy
about 45 miles to the southwest of Diablo Canyon reached
25 feet with an 18-second period at 4 p.m., while the Cape
San Martin NOAA buoy peaked at 24 feet.

This morning’s 12- to 14-foot westerly (280-degree, deep-
water) swell (with a 14- to 17-second period) will decrease
to 10 to 12 feet (with a 13- to 15-second period) by
tonight.

Note: Remember, never turn your back to the sea.

A 6- to 8-foot northwesterly (295-degree, deep-water)
swell (with an 8- to 14-second period) is forecast along
our coastline on Saturday into Sunday.

Gale-force northwesterly winds will generate an 8- to 10-
foot northwesterly (310-degree, deep-water) sea and swell
(with a 5- to 11-second period) on Monday, decreasing to
6 to 8 feet by Tuesday.

A 4- to 6-foot northwesterly (295-degree, deep-water)
swell (with an 8- to 17-second period) is forecast along
our coastline on Wednesday, increasing to 5 to 7 feet
(with an 18- to 20-second period) on Thursday, further
building to 7 to 9 feet (with a 15- to 17-second period)
next Friday and Saturday.

High-swell conditions are expected on January 29 and 30.

ATMOSPHERIC CONDITION:

Dense ground fog has developed throughout the Central
Coast this morning, by will clear later this morning.
Mostly clear to partly skies are expected this afternoon
with high temperatures reaching the mid-60s.

Looking ahead to the Martin Luther King Jr. holiday
weekend, Santa Lucia (northeasterly) winds, dry weather
and mostly clear to partly cloudy skies are forecast
on Saturday. Saturday’s high temperatures
will reach to the high 60s in the North County and low-
70s in the coastal valleys.

A 1,009 millibar low-pressure system will move into far
Northern California but the associated cold front
will move over the Central Coast Sunday evening
with increasing clouds and a few light rain showers.

At this time, this relatively weak system may obscure
viewing of the total lunar eclipse (blood or copper
moon) that will take place with totality of the event
between 8:41 and 9:43 p.m. It’ll coincide with the super
moon, which will be at perigee and will appear
approximately 14 percent larger and 30 percent brighter
than usual. This will also be a wolf moon (first full
moon of the year). Consequently, this will be called a
super wolf blood moon.

This system be will followed by strong to gale-force
(25 to 38 mph) northwesterly winds, night and morning
marine low clouds and cooler temperatures.

High pressure will then build into California for the
rest of next week for fair and dry weather with fog a
good possibility across the coastal and inland valleys.
Dry weather may last for the rest of January.

WILDFIRE DANGER RATINGS:

The rain will keep fire danger low this week and
continue to aide seasonal grass crop growth. Fire
danger is expected to remain relatively low for all
locations over the next week due to recent storms
and increased fuel moisture.

Today’s PG&E Fire Index Ratings are at low levels
along the coastline and coastal valleys and in the
inland valleys.
