6am Surfline significant buoy readings and discussion.
0.6ft @ 18s from 194° (SSW)
Lanai keeps showing low long period SSW energy, but the Lahaina webcam shows flat with very occasional little waves like that. Check it if interested, for size, conditions and consistency.
New long period WNW swell started rising at the NW buoys, but it's still looking quite unimpressive. Here's Pat Caldwell's description of the evolution of the fetch:
Wednesday morning 18Z (8 AM HST) 2/10 synoptic weather chart shows a hurricane-force, 947 mb low pressure near 45N on the Date Line, or about 1800 nm away from Hawaii. This is your text book winter Aleutian low. The low deepened rapidly Tuesday 2/9 though the areal coverage of the strongest winds was still compact. By early Wednesday, the fetch of severe-gale to hurricane-force winds had expanded long and wide over the 305-325 degree band. The head of the fetch is expected to reach about 1200 nm away late Wednesday into Thursday. Highest seas are predicted to aim NE of Hawaii, though a hefty portion is aimed at the islands. With the SW-NE tight gradient of swell size near the islands, place bigger error bars than usual on the local surf estimate.
Below are the maps of Feb 9 through 11 that will help follow.
Below are the graphs of NW101 and Pauwela together with the Surfline forecast. I believe there will be sets noticeable in the afternoon, while Surfline only calls for tomorrow.
Home guess for Hookipa this morning is close to flat with occasional sets up to head high.
Wind map at noon.
While waiting for the usual wind maps to come back online, these are two alternatives: PACIOOS page and Surfline. Another big difference between the two: the first one calls for wind in Kahului, the second shows too easterly of a direction to get down there. I'm still comparing the two.
