Forecast: Cool northerly winds on the way

HONOLULU (HawaiiNewsNow) -

A weakening cold front will cross over Oahu this morning from west to east. Showers associated with the front are scattered and not heavy.

Filling in behind the front will be dry, cool, northerly winds. Those winds will eventually shift to northeasterly trades, perhaps as early as this evening. Trade wind weather will hang around through much of Friday, and then another front will shut off the trades.

The high in Honolulu today will be around 79 degrees.

A new and dangerously large swell will build to extra-large heights by afternoon. The National Weather Service says waves will reach 35 to 45 feet for north shores, 20 to 30 feet for west shores and 2 to 4 feet for east and south shores. Only experts should enter the water and if you are heading out to watch Mother Nature's spectacular show, please use caution and stay well back from the water's edge.

A High Surf Warning is in effect for north and west shores of Oahu, Kauai, Molokai and north shores Maui. A High Surf Advisory is in effect for west shores of the Big Island. A Small Craft Advisory has been issued for most waters due to large open ocean swell.
