Glenn’s Sunday comments:  I’m here at home in upper Kula, Maui

It’s cloudy early this morning, with off and on gusty winds, and a low temperature of 55.5 degrees at my place, and the relative humidity is 75%.

835am, it’s windy here at my place but it’s not crazy yet, and the power is still on thank goodness. The truth is that I expect the power or internet connectivity to go off at some point today. The rain isn’t falling very much, with just off and on generally light showers, nothing crazy in that department yet either.

845am, just in the last 10 minutes we had quite the pile driver gust come through, and I’m afraid we ain’t seen nothing yet!

1045am, the wind has stopped although we’re having a light shower here in Kula

115pm, it’s lightly raining although the winds are calm, now that the winds have taken on a more northeast to easterly direction, putting Kula in the leeward side of the Haleakala Crater.

422pm, cloudy with light rain and calm winds here in Kula, compared to the heavy rains in many windward locations. The high temperature so far today here at my place has been 61 degrees, with the current temperature 58.4 degrees…definitely a chilly day.

548pm, cloudy with light showers and gusty winds…temperature 56.6 degrees at my place.

>>> All State offices and all public schools close Monday, February 9th due to severe weather

I suggest that we all, at least those of us who live in Hawaii, keep our devices charged up as long as possible, in case the power goes out as the winds increase going forward

 

Hawaii’s Broad Brush Weather Overview…as of 319pm: Ample moisture remains over the area thanks to a surface trough (the remains of the cold front) and an upper level low to our west-southwest. This upper low will weaken and slowly drift farther to the southwest and away from the state through Wednesday. A surface high to our north will strengthen overnight, helping keep strong trade winds blowing through tomorrow, with only a little bit of weakening going into Tuesday.

The potential for flooding will remain over all islands tonight and Monday, with the highest chance over windward Maui County and windward Big Island. Strong winds will continue to occur over all islands as well, with the strongest winds in the lee of mountains and in/near stronger showers. There is still a slight chance of thunderstorms through Monday. After Tuesday, trades will maintain above-normal strength, and windward showers will be plentiful, but the high threat potential of today through Monday will end.

 

Flood Threat Outlook: 

What
> Heavy rain leading to flash flooding
Where
> Entire state, particularly windward areas
When
> Sunday into Monday
Impacts
> Flooding of roads, streams, and poorly draining areas

 

Damaging Wind Threat: 

What
> Strong, sustained trade winds 30+ mph
> Gusts 70 mph possible
Where
> Entire state, particularly over and downslope of terrain, through valleys, and other local acceleration areas.
When
> Late today through Monday
Impacts
> Potential for power outages, downed tree limbs
>Weaker trees may be uprooted
> Driving may be difficult in high profile vehicles

Hawaii’s Weather Details…as of 319pm:  Satellite shows overcast skies, which is not surprising given the storm we are experiencing. Radar indicates widespread rain, some heavy, on all islands except Oahu. There, the leeside is relatively rain-free, but a few light showers have appeared through the afternoon so far. Most islands have reported rainfall of over an inch in the past three hours in at least a few locations, and in some cases this heavy rain is widespread. Several locations on the Big Island have reported over 10 inches of rain in the past 24 hours, with a maximum of 14.67 inches at Honokaa. There have been additional mudslides/landslides today, mainly on the Big Island.

Winds were gusty in many locations, especially downwind of higher terrain. Several gusts over 60 mph have been reported (including one over 70!), with widespread reports greater than 40 mph. Numerous trees have been downed and there are many areas without power (although many others have been restored already). A final note on current conditions, today has been quite cool, with the Honolulu airport reporting a high of only 70 so far. Monday will be cool again, with perhaps just a couple degrees of warming compared to today.

An upper level low several hundred miles to the southwest is helping draw plenty of moisture northeast over the state. It is also providing cold temperatures aloft, helping to increase instability leading to isolated thunderstorms. These have remained offshore (to the southwest of Kauai County near the center of the upper level low) so far. At the surface, a 1035 millibar high to the north, combined with a trough of low pressure to the south, has resulted in a strong pressure gradient across the region.

This is bringing us the strong trade winds (generally 20-30 mph with higher gusts) at low levels. These winds become stronger as showers “mix down” stronger winds from a few thousand feet up, where wind speeds are 35-50 mph. They also become stronger as winds move down mountain ranges, where a “mountain wave” can occasionally form. This process can produce wind gusts at or above 60 mph.

The upper low will remain nearly stationary tonight, then slowly drift southwest as it weakens through Wednesday. At the surface, the high to the north will intensify tonight, helping to increase winds across the state. The High Wind Warning for most areas will remain in effect through 6pm Monday. Rain will continue through the night and into tomorrow as well, so the Flood Watch will also remain in effect through 6pm Monday. The heaviest rain is still expected across windward areas, with light to moderate rain elsewhere. Snow will continue on the summits of Big Island, therefore the Winter Storm Warning there will continue

Looking farther into the future, the surface high will undergo evolution as one center weakens and another takes its place, but the result will be a continuation of moderate to strong trade winds through the upcoming week. We will see significantly less widespread precipitation starting Wednesday, but windward areas will see numerous showers through the end of the week.

Hawaii’s Marine Environment:  A trough currently over central waters, a developing low pressure several hundred miles southwest of the islands and strong high pressure building north of the front, is driving these strong to gale force northeast trade winds along and north of the feature. A Small Craft Advisory (SCA) remains in effect for all Hawaiian waters due to a combination of winds and large. A Gale Warning will be in effect starting this morning through Monday afternoon for all coastal water zones for winds and seas. In addition, expect heavy showers and isolated thunderstorms through Monday. Winds are expected to ease some on Tuesday, but trade winds will remain in the strong range with some locally near gales over the windier waters and channels through the forecast period.

The current moderate west-northwest swell (295-310 degrees) will continue to gradually decline through Monday. The High Surf Advisory (HSA) has been cancelled for all north and west facing zones. Small to moderate north-northwest to northwest swells will prevail through the remainder of the week.

Large and very rough seas will begin to develop as trade winds strengthen. East shore surf should rise above the HSA threshold tonight, with the potential for surf to reach the High Surf Warning (HSW) level Monday and Tuesday on Kauai and Oahu. Large east shore surf will slowly decline Tuesday into Wednesday, but will still remain somewhat elevated through the remainder of the week. Surf along south facing shores will remain small with some small background south-southwest energy expected throughout the first half of the week. Select southern exposures exposed to the wind swell will likely see some larger waves as well.

Interesting:  As the Arctic Gets Louder, Narwhals Are Going Quiet

In a warming Arctic, noise from growing shipping traffic is interfering with the ability of narwhals to hunt and communicate.

For most of their evolutionary history, narwhals have relied more on sound than sight to survive in the Arctic’s dark icy waters.

The speckled toothed whales — sometimes referred to as “unicorns of the sea” for the long, spiral tusks that protrude from the heads of males — navigate, hunt, and communicate using echolocation. By emitting a series of calls, whistles, and high frequency clicks — as many as a thousand per second — and listening for the echoes that bounce back, they are able to locate prey hundreds to thousands of feet deep and detect narrow cracks in sea ice where they can surface to breathe.

But as global temperatures continue to rise, the acoustic world narwhals depend on is rapidly shifting throughout their range, from northeastern Canada and Greenland to Norway’s Svalbard archipelago and Arctic waters in Russia. It’s getting louder.
