An unseasonably strong upper low will move over the islands on Friday, bringing in very unstable air for this time of year. This will be enough for a few heavy showers or thundershowers to develop in some spots. Most of these should be relatively brief, so while widespread flash flooding is unlikely, ponding of water in poor drainage areas, and maybe even some small hail, could occur in a few of the heavier downpours Friday and Friday night.

...FLOOD WATCH IN EFFECT THROUGH THIS AFTERNOON FOR MOST HAWAIIAN ISLANDS... * WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, and Maui. * WHEN...Through this afternoon. * IMPACTS...Flood prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff. * ADDITIONAL DETAILS... - An unseasonably cold upper level low moving into the Hawaiian Islands from the north will produce periods of heavy showers across the island chain today. The center of the low will settle in over Kauai around noon HST, the low will then weaken and drift slowly eastward tonight. Unstable conditions within this upper low will likely produce periods of thunderstorms and heavy showers, potentially leading to flash flooding conditions in some areas. This Flood Watch may need to be extended into the overnight hours for some counties.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

Lava fountaining from Kilauea eruption episode 47 started this afternoon at 3:27 PM HST and continues this evening. The latest radar imagery shows the highest detectable ashfall (tephra) from the lava fountaining is currently rising to around 8,000 feet above ground level this evening. Low level trade winds continue to push the ashfall particles toward the southwest direction on radar, and any additional ash from this eruption will likely fall near the Kilauea eruption source and over portions of the Kau District immediately southwest of Halemaumau Crater. Avoid excessive exposure to ash which is an eye and respiratory irritant. Those with respiratory sensitivities should take extra precaution to minimize exposure.

...MINOR COASTAL FLOODING ON ALL ISLANDS DURING HIGH TIDES THIS WEEKEND INTO EARLY NEXT WEEK... .Peak monthly high tides combined with water levels that will be running higher than predicted will lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the daily peak tides, which will occur during the late afternoon hours. * WHAT...Isolated minor coastal flooding expected. * WHERE...Vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure of all Hawaiian Islands. * WHEN...During the afternoon hours this weekend into early next week. * IMPACTS...Flooding of beaches that are normally dry, minor coastal erosion, and saltwater inundation.

Avoid driving through flooded roadways. If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water. Move electronics, vehicles or other valuables to higher ground. Monitor vessels to ensure mooring lines don't get too tight and watch out for overwash around boat ramps. Secure canoes or other watercraft stowed on beaches.
