Pathway in the Sea

Ever see a butterfly flutter by? John 3:7-8

Psalm 77:19

Thy way is in the sea, and thy path in the great waters, and thy footsteps are not known.

"The best way to show that a stick is crooked is not to argue about it or to spend time denouncing it, but to lay a straight stick along side it."

-D. L. Moody

Psalm 93 The Lord reigneth, he is clothed with majesty; the Lord is clothed with strength, wherewith he hath girded himself: the world also is stablished, that it cannot be moved.
Thy throne is established of old: thou art from everlasting.
The floods have lifted up, O Lord, the floods have lifted up their voice; the floods lift up their waves.
The Lord on high is mightier than the noise of many waters, yea, than the mighty waves of the sea.
Thy testimonies are very sure: holiness becometh thine house, O Lord, for ever.

100 ft Wave - Storm 8
(November 21, 2001; Fading La Nina)

Storm 8 generated the largest swell on record, beating out the huge Hawaiian El Nino swell of 1/28/98. Forecast to be a rather local and moderate storm that was to track over buoy 46006 (SE Papa) like Storm 1 in 1999, what actually hit was beyond imagination.
Days earlier 2 storms were forecast to move in quick succession into the Gulf of Alaska. As expected, the first one developed and followed the forecast track, generating a swell that started to hit the outer SE Papa buoy (46006) on 11/19 at 11 AM with seas in the 20-23 ft @ 17 secs. This swell reached Mavericks the afternoon of November 20th with seas 13-14 ft @ 14-17 secs with swell 10.5 ft @ 15.5 secs, holding through the night. Nothing noteworthy but defiantly rideable at Mavericks. While the first storm took up residence in the Gulf and slowly faded, a second storm followed quickly in it's tracks on November 19th. It developed a small but relatively intense fetch area in it's south quadrant with winds at 55-60 kts blowing due east, carried by the jetstream and fueled by the moisture left behind by the first storm. These winds found lot's of traction at the oceans surface, already agitated from the earlier storm. The new storm also tracked east at a very fast pace, not allowing the developing seas to escape the influence of it's winds, piling more wave energy on top of an already large swell (virtual fetch). By the morning of 11/20 winds were still being recorded with speeds at 55-60 kts. The northern component of the resulting swell hit buoy 46006 at 9 AM and held through 7 PM with seas ranging 38.5-41.9 ft @ 17-20 secs, very large but not off the scale. Clearly, this buoy did not get hit with all the wave energy this storm had produced, with much of it passing south undetected. And buoy 46059 located 350 nmiles off Pt Reyes was out of service, further reducing the effectiveness of the normal early warning system.
Nearshore the situation got interesting. On the morning of 11/21, the swell from the first storm was still present at buoy 46012 (Half Moon Bay) with decoded swell at 12 ft @ 15 secs. As expected, by 10 AM the second swell started to build in with combined seas 16.4 ft and the new swell at 11.1 @ 20 secs and increasing rapidly. The paddle-in crew was out cautiously catching some bombs as the swell jumped in size with each passing set. The tow teams waited in the channel for their chance to strike. By noon they got their chance as the last paddle surfers were cleaned out and increasing south winds took a toll on conditions. Combined seas were 19.6 ft @ 20 secs with solid energy out to 25 secs and swell 14.1 ft @ 19 secs. One hour later swell was up to 14.9 ft @ 19 secs. By now the tow teams were only shoulder hopping the huge sets that were pouring over the reef while south winds set up a strong northerly crosschop. Even so, Carlos Burle managed to snag the biggest wave of the year, measured at 68 ft on the face. The swell was interacting with the 15 second swell already present, creating huge waves breaking way outside the normal outermost reefs. By 2 PM the new swell was up to 16.3 ft @ 19 secs, then up to 19.3 ft @ 21 sec one hour later. Shawn Alladio was out in the channel on a jetski at Mavericks and reported nearly being taken out by a set of waves the largest being upwards of 100 ft. Based on the buoys, even larger waves followed after she made it safely to shore. By 5 PM the largest decoded swell reading hit, with swell at 19.9 ft @ 19.4 secs and combined seas to 23.98 ft. Whitewater was visible out to the horizon at most coastal locations, and longtime locals reporting breaks they had never seen were going off, but way beyond anything that would be classified as rideable.
