Swell Summary
Moderate trades weaken and veer to SE from Oahu and points east and S in the vicnity of Kauai tonight as low pressure tracks well N of the area. The attendant cold front enters the western waters Sunday night where there will be a slight chance for thunderstorms. Moderate winds retain a SE component through mid- week.
The current large, medium period NW swell is tracking close to model guidance and has declined sharply since its early morning peak at the Hanalei and Waimea buoys. Surf has fallen below the advisory threshold for all shorelines and High Surf Advisories (HSA) have been allowed to expire. Small surf expected Sunday as this swell steadily diminishes. Deep low pressure presently situated just southeast of Russia's Kamchatka Peninsula will deliver a large, long period swell WNW (310) swell early next week with long period forerunners arriving by Sunday night. The distant source region of this swell compared to the present swell will focus energy in the longer period bands increasing confidence that surf will rise to well within the HSA range during Monday and perhaps approach warning criteria for N and W facing shores as it peaks Monday night through Tuesday. The swell then gradually subsides during the second half of the week.
Moderate SE flow maintains small chop along E facing shores while background energy out of the southerly quadrant maintains small surf for S facing shores.
