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 1007am Sunday: A powerful kona storm will impact the state this coming week into next weekend, and will bring numerous impacts across the state. A combination of flash flooding, strong and gusty southerly winds, thunderstorms possibly severe at times, will threaten Hawaii starting over Kauai on Tuesday, and spreading statewide from Wednesday into next weekend. Island by island impacts will be driven by both large scale troughs and smaller scale thunderstorm bands over the entire duration of this severe weather event.

Short Term Update…as of 10am Sunday: Forecast remains on track with moderate to breezy east to east-southeast winds today with some scattered showers over windward areas. Winds are expected to gradually decrease tonight into Monday and veer slightly more towards the southeast. This should allow for some sea breezes to develop during the day on Monday for select areas, with some scattered showers especially in the afternoon.

Hawaii’s Weather Details…as of 410am Sunday: Looking into the satellite picture this morning we see unstable cumulus clouds riding into the eastern windward slopes of island mountains. Clouds and passing showers will continue through the morning hours for these mountain areas. Farther away near the International Date Line to our west, a very large upper low with surface cold front continues to deepen, and will slowly bring significant weather impacts to the Hawaiian Islands lasting for several days this coming week.

This strong low pressure system is already showing a long reach with associated weather impacts far from the center of the storm. A significant band of thunderstorms continues to develop roughly 500 to 700 miles east to southeast of the low`s center. A band of high level clouds even farther away from the low, shows embedded thunderstorms forming just 150 to 250 miles west of Kauai. Strong divergence under an upper level trough and dynamic lift from a 150 MPH jet stream, will slowly drive these heavy showers and thunderstorm bands into Hawaii beginning Tuesday and continuing into next weekend.

The latest model guidance continues to show good consistency with the track and intensity of this large storm into next weekend, adding confidence to our statewide impacts forecast. A combination of upper level divergence and low level convergence will produce deep convection from abundantly unstable moisture, riding northward into the islands from the deeper tropics. Passing upper level troughs will provide more efficient divergence aloft and a higher degree of lift for heavy showers and thunderstorms over the islands during this event.

The highest threats start with heavy rain that may cause flooding to develop over the western half of the state on Tuesday, these heavy rain threats then rapidly spread eastward becoming statewide flood threat impacts from Wednesday into the weekend. A statewide Flood Watch will likely be issued over the next couple of days, to cover these heavy rain and potential flooding impacts. Storm total rainfall amounts from Tuesday through Saturday are 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. Expect very saturated soil conditions to develop over the first few days, accelerating the flooding threats by the second half of the week, as less intense rainfall on saturated ground will quickly produce water runoff that leads to flooding concerns. A Hydrologic Outlook remains in effect for these flood threats later this week.

The next impacts are related to the developing southerly to southwesterly kona winds. A deep surface low approaching the islands will cause the wind directions to veer from a southerly direction from Tuesday onward. Initially Wind Advisory threats are possible due to strong wind gusts developing north of steep mountain slopes of all islands. These gusty winds may knock down trees in saturated soil conditions that weaken root systems, making them vulnerable to atypically strong southerly winds.

Southerly to southwesterly kona wind speeds will significantly increase into high end advisory or even exceeding warning thresholds from Friday into next Sunday. Damaging winds are likely during this time period mainly over northern and easterly slopes of steep mountain ranges of all islands. Power outages should be expected mainly caused by falling tree branches on power lines.

Additional wind threats on the smaller scale will be driven by strong thunderstorms that will form rapidly in the southerly kona winds. These storms will produce bands of heavy rain and thunderstorms. Significant atmospheric instability and wind shear aloft will set the stage for some of these stronger thunderstorms to become severe. The main threats from severe thunderstorms will be strong damaging wind gusts, very high rainfall rates, and dangerous lightning. A Severe Thunderstorm Watch may be needed at some point during this event to cover these threats.

High elevation snow and ice with stronger winds are also expected over the highest elevations of Mauna Kea and Mauna Loa on the Big Island. These conditions will likely limit road access to the observatories at summit level.

Please plan ahead for these significant statewide weather impacts over a five day time period lasting into next weekend.

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.
