Honolulu is currently experiencing stable and mostly dry conditions, with light winds set to continue throughout the day. According to the National Weather Service in Honolulu, a fast-moving cold front is predicted to bring a brief shower spree across the islands from late tonight into Monday. A second, more formidable front is forecasted to hit Wednesday into Thursday, potentially bringing heavier rainfall in some localized areas.
Today's clement weather will give way as the cold front moves in starting tonight, with Kauai first on the list to witness increased showers accompanied by moderate southerly winds. The front is expected to swiftly traverse the island chain, reaching Oahu by Monday morning. The passage will result in cooler, drier air and a drop in temperatures across the smaller islands - making Tuesday morning to start off as a chilly affair by local standards, as reported by the National Weather Service.
Aviation authorities anticipate stable and VFR (Visual Flight Rules) conditions through the day, but a cold front sweeping through the western end of the state tonight will likely trigger MVFR (Marginal Visual Flight Rules) conditions due to increased cloudiness and showers. The advent of the front means that breezy northerly winds are following behind it and will usher in drier conditions post-passing.
For mariners, a Small Craft Advisory is currently in force due to a northwesterly swell resulting in combined sea levels of around 10 feet, as stated by the National Weather Service. Furthermore, a High Surf Advisory is extended until Monday morning for certain shores, with surf anticipated to rise to High Surf Warning levels from Monday through Tuesday due to an overlapping northwestern swell. A subsequent extra-large northwest swell is predicted to generate even higher surf levels along north and west facing shores by Thursday.
The local marine community should also brace for strong to near gale force winds expected later in the week as the second cold front moves over the islands. Beachgoers are warned that north and west facing shores will likely experience high surf conditions until Friday before the energy abates heading into the weekend. Surf along east and south facing shores will stay minimal throughout the forecast period.
