And so, it almost begins.....

As of Early August, most experts have officially announced a strong El Nino is in play.  The warm water we're experiencing actually has nothing to do with El Nino, rather the lack of heavy northwest winds this summer kicking off upwelling and more about the ongoing southerly flow of wind which tends to increase water temps around these parts.  Elsewhere in the Pacific, subsurface warm water along the equator - stretching west to east and north and south with some key areas El Nino experts monitor  - much warmer than usual  - (referred to as the Nino 3.4 and Nino 1.2 regions) and West Pacific Cyclone Molave forecast to recurve and turn extra tropical to bring us potentially our first longer period west/northwest swell of the season next week.  If that system tracks as forecast we can see surf week of 8-24.  The northern branch of the Pacific jet stream is more active than normal for August - not remarkable, but certainly more energetic than you would find this time of year.  What's it all mean for us?  Well, hopefully copious amounts of rain - but that's not always a sure thing with an El Nino, where the southern branch of the jet stream can get move active and bring weather into So Cal.  But recent history has proven we get plenty of rain, 1997, 82 and smaller events.  High elevation snowpack - due to warm storms, high snow levels.  Good for water supply, bad for most Tahoe ski resorts.  Plenty of swell, but could come with a lot of weather as storms form close offshore and barrel through.  Will update on Typhoon Atsani early next week.  Then look for official forecasts weekly to start up in September.  Cya in the water.
