Detailed Forecast

Update

Currently at the surface, a slow moving cold front is located in the Kauai Channel just east of Oahu as of 8 pm HST. Behind the front moderate to breezy north winds have filled in with gusts as high as 40 mph reported at Barking Sands within the past couple of hours. Ahead of the front light and variable winds prevail. Infrared satellite imagery depicts mostly cloudy to overcast conditions across the smaller islands, while partly to mostly cloudy skies are present on the Big Island. Radar imagery shows scattered to numerous showers across the smaller islands, with fewer showers over the Big Island. Main short term focus revolves around rain chances and the potential for some heavy rain tonight in Kauai.
The front will move slowly southeastward through Oahu and into Maui County tonight, with scattered to numerous showers accompanying the feature, and breezy north to northeast winds filling in behind it. Thus far rainfall intensity has remained under control, although there is some concern that it could increase particularly over the north coast of Kauai later tonight where it will be enhanced by orographic lift provided by the strong northerly flow. We will monitor rain/stream gauges closely through the night for potential need for flood advisories. Update will be sent out shortly.

Synopsis

A cold front will move through Oahu tonight, then slow and stall near Maui County by early Saturday. This frontal boundary combined with increasing moisture and a disturbance aloft, will bring the potential for heavy rainfall, flash flooding, and a few thunderstorms from Saturday afternoon through Monday. Breezy north to northeasterly winds will develop behind the front, then the trades will become very windy late Sunday into Monday as strong high pressure builds well north of the state and interacts with a deepening trough to the west. Conditions will gradually improve by mid to late next week, though breezy and occasionally showery trade wind weather is expected to persist.

Aviation

– UPDATED 830 PM HST Fri Feb 6 2026
A strong cold front is moving through the island chain and a separate band of moisture is moving southwest to northeast over Maui County. The front is bringing low cigs, SHRA and strengthening north winds to Kauai and Oahu this evening, with Maui County overnight and the Big Island tomorrow. IFR to MVFR conds expected, with localized LIFR conds, with FROPA.
AIRMET Sierra is in effect for mtn obsc from Kauai to Maui and will likely linger overnight. It will most likely be expanded to the Big Island tomorrow. If conds deteriorate further Sierra may be needed for IFR conds.
AIRMET Tango for mod turb will likely become necessary overnight and Saturday as winds increase, starting with Kauai and spreading eastward.

Marine

A front currently near Kauai will move to Oahu waters tonight, then stall and dissipate over Maui County waters Saturday. High pressure building behind the front will produce fresh to strong northeasterly trade winds around Kauai and Oahu tonight and expand to Maui County waters Saturday. A Small Craft Advisory (SCA) remains in effect around Kauai and Oahu for a combination of the increasing winds and combined seas in excess of 10 feet from a building west-northwest swell. The SCA has been expanded to Maui County waters Saturday. Over Big Island waters, gentle to moderate southerly winds will give way to strengthening easterly winds on Saturday. As the high expands later in the weekend, trade winds will strengthen to near gale to gale force over most waters late Sunday and Monday. While the SCA now runs through Sunday afternoon, it will need to be expanded to all Hawaiian waters and extended through at least Monday, and a Gale Watch may be issued overnight for some waters. In addition, expect heavy showers and isolated thunderstorms over most waters Saturday through Monday. Winds are expected to ease Tuesday but still remain in the fresh to strong range through Wednesday.
A large west-northwest swell (295-310 degrees) will build down the island chain through the evening and peak late tonight into early Saturday. Recent observations at NOAA buoys northwest of Kauai indicate that the swell is coming in a couple of feet larger than guidance at 14 to 16 feet with significant energy spread between 13 to 19 second periods. A High Surf Warning (HSW) remains in place for rapidly rising surf across north and west facing shores of Niihau, Kauai, Oahu, and Molokai this afternoon and evening, and given the larger swell, the HSW has been expanded to north shores of Maui. The swell will reach west facing shores of the Big Island around sunrise, and a High Surf Advisory is in effect for that area through at least the afternoon. The swell will decline sharply late Saturday, with surf expected to fall below advisory levels on all shores by Sunday morning. Small to moderate north-northwest swells will prevail through the remainder of the week.
Surf along east facing shores will remain very small into the evening. East shore surf will build and become rough from west to east late tonight and Saturday as the front moves down the island chain. Large and very rough seas will develop on Sunday as trade winds strengthen, likely exceeding the advisory level Sunday night or Monday and potentially reaching the warning level. Large east shore surf will slowly decline Tuesday through the remainder of the week. Surf along south facing shores will remain small with a slight bump possible early next week.

Prev discussion

/ISSUED 345 PM HST Fri Feb 6 2026/
Visible satellite imagery this afternoon highlights two key features impacting the forecast: a cold front on Kauais doorstep and a plume of moisture lifting northward across the central islands within a weakly convergent southwesterly flow.
The cold front is expected to move across Kauai late this afternoon or early this evening, then continue gradually down the island chain toward Oahu late tonight before slowing and stalling near Maui County on Saturday. Shower coverage will increase along and ahead of the front, with the greatest potential for heavy rainfall tonight across north- and east-facing areas of Kauai. Some high-resolution model guidance suggests rainfall totals of 1 to 3 inches in these areas by Saturday morning. Meanwhile, isolated to scattered showers will continue to filter across the central islands on the weakly convergent southwesterly flow. As the front reaches Oahu late tonight and Maui County on Saturday, showers will increasingly focus over windward and mauka areas.
As the front stalls and begins to weaken over Maui County on Saturday, it will interact with the weak surface convergence zone embedded in the southwesterly flow ahead of it. This interaction will lead to expanding shower coverage statewide. With deep moisture supplied by these two features spreading across the islands and increasing instability as much cooler air filters in aloft with an upper level disturbance, the threat for heavy rain and flooding will rise, particularly over windward and mauka areas. Model guidance suggests that some of these areas may receive 3 to 6 inches of rain from tonight through Monday. Isolated thunderstorms will also be possible within the more robust shower bands. A Flood Watch remains in effect for all islands from noon Saturday through 6 PM Monday.
In addition to the flooding threat, winds also become a concern Sunday into Monday as high pressure builds in behind the front and a surface trough forms and deeps west of the state. The tightening pressure gradient between these surface features will strengthen the trade winds likely to Wind Advisory criteria late Sunday into Monday, with the potential for isolated High Wind Warning level gusts across some leeward downsloping areas.
Finally, winter weather impacts are possible for the Big Island summits this weekend. As deep moisture overspreads the island, an upper level disturbance nudges in from the northwest, and temperatures aloft drop below freezing, conditions will become favorable for heavy snowfall at the summits. As a result, a Winter Storm Watch remains in effect for the summits of Mauna Kea and Mauna Loa from Saturday afternoon through Monday afternoon.
Conditions will gradually improve for the middle and latter portion of next week, although a somewhat showery and breezy trade wind pattern will likely persist.
