Of much interest is confirmed development of low pressure in the Gulf of Alaska on Friday (7/4) which produced 35 kt winds and 19 ft seas aimed right at Central CA. Swell to result for the Pacific Northwest on down into Central CA on Monday (7/7). No storms of interest are forecast for the next 7 days in the southern hemisphere with strong high pressure in control of the upper levels of the atmosphere over the Southwestern Pacific. The last in a series of small storms pushed up through the Tasman Sea Thurs/Fri (6/27) offering limited background swell for California Tues (7/8). A very quiet pattern forecast for the southern hemi but longterm the model suggest the upper level high pressure barrier might start to break down under New Zealand late this week (7/11) offering an opening at the surface for gale development. But it remains way too early to believe this with any certainty. |
