High Surf Advisory
Issued by the National Weather Service at 2:42 am PST on March 11, 2010
... High surf advisory in effect from 10 am this morning to 10 am
PST Friday for the north and central Washington coast...
Large swells of 20 feet will reach the central and North
Washington coast by later this morning. Swell heights will build
and remain in the 20 to 24 foot range this afternoon through
Friday morning before slowly subsiding below 20 feet Friday
afternoon.
Precautionary/preparedness actions...
A high surf advisory means that high surf will affect beaches in
the advisory area... producing rip currents and localized beach
erosion. It is extremely dangerous to fish or observe waves from
rocks during high surf conditions. Unwary beach walkers can be
caught off guard as waves suddenly race farther up the beach than
normal.
