This weekend we had a Blizzard Warning – for Hawaii. It was only for the high peaks (Mauna Kea and Mauna Loa) on the Big Island of Hawaii, but above 13,000 feet, it’s nasty. Snowfall could reach “12 or more” with winds of up to 100 mph. Of course, even wet heavy snow could drift significantly with winds that strong. There have been periods of zero visibility on the mountaintops.

Heavy rain continues to fall and their is now a State of Emergency for the islands. The NWS says there is the potential for “catastrophic flooding.

Also: The main airport on the island of Maui was without power Sunday night. Astronomical high tides and high surf pushed sand and debris onto Kamehameha Highway Sunday morning, near Kualoa Ranch and Oahu’s North Shor

Update: Saturday, the temperature at Honolulu never got about 70° – that’s a relatively cool day for them. Kilohana had 6.73″ of rain in 24 hours. Now that’s a heavy rain! At 5 pm Saturday Hawaii time, Mauna Kea reported a temperature of 28, zero visibility and a south wind at 55 mph – peak gust 83 mph. The wind chill there was 8°.

2nd Update: Sunday the temperature stayed in the 60s in Honolulu – pretty cool for them. They had only 0.12″ of rain, but more rain is on the way for them. Hilo had 1.48″, Molokai recorded 3.19″ and the highest total I saw Sunday evening was 6.54″ at Keaumo. Flood Warnings were issued for the Maui, Molokai and the Big Island of Hawaii.

Warnings and Advisories in Hawaii

There’s also a High Wind Warning (for the mountaintop areas), a Gale Warnings and Small Craft Warnings (for most of the island waters). There’s a Wind Advisory for the island of Kauai and a Flood Watch for most of the state. High surf is likely, with waves up to 14 feet possible.

Much of Hawaii has been on the dry side, especially the Big Island. Hilo received less than 40% of average rainfall in November. Kailua had only 12% of average rainfall in Hawaii. The wet pattern should stick around for at least a week.
