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

It’s clear to partly cloudy early this morning here at my location, with a chilly low temperature of 47.5 degrees, and the relative humidity is 84%.

1240pm, variable clouds here in Maui County, ranging from quite sunny to mostly cloudy depending upon the area. The haze level improved overnight into earlier this morning, although is increasing again this afternoon.

403pm, partly cloudy with some cloudy areas…and it’s hazy.

 

Hydrologic Outlook as of 408am Sunday – National Weather Service Honolulu HI:

HEAVY RAIN AND FLASH FLOODING POSSIBLE FROM TUESDAY INTO NEXT WEEKEND…A large low pressure system developing northwest of the state over the next couple of days will pull a very moist southern air mass northward across the state. This will likely initiate periods of heavy rain and occasional thunderstorms that will increase the probabilities of flooding over Kauai County and Oahu from Tuesday onward. The flooding threat will likely expand eastward to include the entire state from Tuesday night into next weekend.

Storm total rainfall amounts from Tuesday through Saturday are currently forecast to range from 4 to 12 inches across the state during this five day time period. Locally higher amounts are possible, likely driven by slow moving strong thunderstorms or heavy rain bands.

Stay weather aware the next several days as this system develops and the details of the impacts become more clear. The next couple of days would be a good time to clear storm drains and culverts of debris, or anything else that can block the flow of water.

 

NWS Weather Prediction Center as of Sunday: 

Prolonged and Potentially Significant Flash Flood Threat Developing This Week

A major weather change is on the horizon, as the prevailing dry and stable east-southeast trade flow is replaced by an exceptionally moist and unstable Kona wind pattern. This system will be slow-moving, again leading to higher than normal confidence for early March…in a multi-day heavy rain event for Hawaii.

This system will tap rich tropical moisture northward across the islands. Precipitable moisture is expected to range generally between 1.8-2.0 inches Tuesday through Thursday. However, a more impressive deep-layer moisture plume is anticipated Friday through the weekend, when precipitable moisture spikes to between 2.0-2.3″ across the entire State.

Certainly all of the ingredients will be in place for potentially significant flash flooding by mid-late week and through the weekend, especially as soils become saturated and stream/reservoir levels rise across all islands. Next weekend will be of particular concern, particularly over the western and central Islands. This will be several days into this multi-day event, with already saturated soils and high stream levels, when the  low-level southwesterly kona wind flow and moisture flux will be greatest per the model guidance.

Hawaii’s Broad Brush Weather Overview…as of 410pm Sunday: A powerful kona storm will move in across the state this coming week into next weekend and will bring numerous impacts across the state. A combination of flash flooding, damaging winds, strong thunderstorms possibly severe at times, will threaten Hawaii from Wednesday through at least Saturday. The threat for flash flooding could begin as early as Tuesday over Kauai. While island by island impacts will be driven by where the bands of thunderstorms develop, leeward areas of the smaller islands currently seem to be the most favorable areas due to the kona winds.

Hawaii’s Weather Details…as of 410pm Sunday: Currently at the surface, a storm force low is centered roughly 1400 miles northwest of Kauai. In the upper levels of the atmosphere, we are seeing a blocking pattern with a large high centered over the Aleutian Islands and an upper level low below it (northwest of the state). This blocking pattern has been producing numerous bands of thunderstorms over the Northwest Hawaiian Islands over the past few days. As the upper level high strengthens over the Aleutian Islands the next few days, this will allow the upper level low to shift closer to the state and will bring a prolonged period of heavy rainfall, strong to severe thunderstorms, and potentially damaging winds across the state.

Starting late Tuesday, southerly winds will begin to strengthen with an approaching upper level low. Latest global model guidance is in good agreement with low level moisture increasing over Kauai throughout the day Tuesday and spreading towards Oahu Tuesday night into Wednesday. The threat for flash flooding will be increasing during this time, but it is expected to amplify during the day Wednesday, as the threat for strong to severe thunderstorms increase over the western half of the state.

It is with these thunderstorms, where we could see intense rainfall rates, which can quickly lead to flash flooding and also damaging winds. While the western half of the state has the best chance for strong to severe thunderstorms on Wednesday, a threat for thunderstorms will exist all across the state. Currently a Hydrologic Outlook is in effect for the entire state due to the threat of flash flooding. This Hydrologic Outlook should be replaced by a Flood Watch for the entire state by Monday afternoon.

While the threat for flash flooding and strong to severe thunderstorms tops the list for Wednesday, strong southerly winds will also develop, which could cause some gusty winds over our typical windward areas. Winds may reach advisory threshold, but confidence remains low at this time.

While our first wave of moisture begins to move further north on Thursday, strong southwest flow aloft and breezy southerly winds at the surface will continue to bring moisture across the state. Unstable conditions will continue to allow for the development of numerous showers and thunderstorms throughout the day Thursday, although models are showing a slight decrease in coverage of showers and thunderstorms on Thursday. So some areas could see a slight break in action on Thursday.

From Friday onward, models have shifted with the latest guidance and is now showing the possibility of a widespread damaging wind event, as well as another round of strong to severe thunderstorms. Deep tropical moisture will also move in during this time with precipitable water values exceeding 2 inches. Deep tropical moisture, deep shear from the approaching upper level low, and a vigorous trough could lead to a very dangerous period of severe weather Friday into Saturday and possibly continuing into Sunday for select areas.

Now is the time to plan ahead for these significant statewide weather impacts. Some simple things to mitigate damages could be things such as cleaning your rain gutters and drains to prevent debris build up, secure your outdoor items to protect them from high winds. Lastly, please prepare for power outages and have extra nonperishable food, medication, water, etc… Be safe this week!

Hawaii’s Marine Environment…as of 410am Sunday: Strong high pressure far northeast of the state will maintain fresh to strong trade winds. A Small Craft Advisory (SCA) is now in effect for most marine zones through 6pm today, and for most central and eastern waters through 6am Monday. A front approaching from the west will begin to ease the trades and shift them southeasterly on Monday, with the winds then becoming southerly and increasing to fresh to strong levels Tuesday through late in the week.

Surf along east facing shores will remain elevated and choppy, trend downward on Monday, then fall below normal levels Tuesday through late in the week.

A series of west-northwest swells will keep some small surf in place along north and west facing shores during the next 7-days, but surf will remain well below advisory levels. A small to moderate sized north swell is possible late in the week.

Surf along south-facing shores will remain small, with the exception of areas exposed to trade wind swell wrap. Rough and choppy conditions will develop Tuesday and continue through late in the week, as southerly winds increase in advance of a cold front. A series of small long period south swells will also move through Monday through late in the week.

Interesting:  Hunting Pressure is Shrinking Safe Space for Mandrills in Equatorial Guinea

Researchers from the University of Bristol Veterinary School, in collaboration with Bristol Zoological Society and partners in Equatorial Guinea, have uncovered alarming evidence that hunting pressure is dramatically reducing the safe habitat available to mandrills inside Monte Alén National Park, one of Central Africa’s most important rain forest strongholds.

Mandrills, the world’s largest and most colorful monkey species, are listed as Vulnerable by the IUCN and face growing threats from habitat loss and hunting. Despite their crucial role as seed dispersers and indicators of forest health, the species remain poorly studied across much of their range. This new study reveals that even protected areas are failing to offer full refuge.

Using 35 camera traps deployed by Bristol Zoological Society’s Equatorial Guinea Conservation Program, researchers monitored mandrill presence across the park and the impact of environmental and human influences on their movements.
