Fresh and gusty trade winds beneath a well defined inversion aloft are expected to persist today. Wind speeds in excess of 25 kt are expected along northeastern exposures and over mountain ridges, with some local channeled areas potentially experiencing stronger wind gusts. As a result, airmet tango remains in effect for moderate low-level turbulence in the air space leeward of all mountains today.

Trade wind showers are expected to continue affecting mainly windward facing slopes and terrain. Low clouds and numerous showers across the northeast Big Island have required the issuance of airmet sierra for mountain obscuration over the windward Big Island. These conditions are expected to persist beyond sunrise this morning. Brief MVFR cigs may also occur along some windward sections of the smaller islands, especially Maui. Otherwise, VFR conds are expected to prevail across most other areas through this afternoon.
