Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

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

949pm, I’m back Sunday evening, after having no power or internet connectivity since this past Friday afternoon!

521am Monday morning, there’s no wind, although there’s dense pea soup fog here early this morning at my place, with the low temperature a relative warm 59.5 degrees, along with the relative humidity 81%.

406pm, off and on foggy periods with drizzles here in upper Kula today, with radar showing a somewhat more substantial shower area taking aim on the leeward sides of Maui County late this afternoon.

515pm, fog rolling in and it looks like a small band of showers will follow in its tracks…here in leeward Maui County

847pm, mostly cloudy although dry here at my place, with the temperature 62.9 degrees, and with the relative humidity 76%

 

>>> Highest Temperature Monday, March 16, 2026 – 99 degrees near North Shore, CA
>>> Lowest Temperature Monday, March 16, 2026 – minus 15 degrees at Langdon, ND

 

Hawaii’s Broad Brush Weather Overview…as of 842pm Monday: Unsettled weather will persist across the Hawaiian Islands through the week in the wake of the recent kona storm. Although a brief lull in widespread heavy rainfall is expected through mid-week, deep tropical moisture will remain in place and support periods of showers, particularly over the eastern end of the state. Conditions are expected to deteriorate again during the second half of the week, as another upper-level disturbance and surface low approach from the west, bringing increasing chances for widespread rainfall and renewed kona winds. With soils already saturated, additional rainfall could quickly lead to runoff and flooding impacts.

Hawaii’s Weather Details…as of 842pm Monday:  In the wake of the significant kona low that impacted the state over the past several days, a broad and persistent upper-level trough remains anchored over the region. While the kona low has weakened and lifted away, the larger-scale pattern remains largely unchanged, with deep tropical moisture continuing to stream northward over the state. Precipitable water values remain anomalously high, maintaining a moist air mass across the state.

Model guidance continues to indicate a relative decrease in widespread heavy rainfall through the next couple of days, particularly over the western end of the state. However, this should not be interpreted as a return to benign conditions. Periods of showers will persist within the moist/deep southwesterly kona wind flow, with locally heavy rainfall still possible, especially across Maui County and the Big Island, where the axis of deepest moisture is expected to remain focused through mid-week.

By the latter half of the week, the upper-level trough is forecast to deepen west of the state. This feature is expected to re-expand the axis of anomalous moisture back across the entire island chain, while increasing large-scale ascent. At the surface, low pressure is forecast to develop and approach the islands, with potentially breezy kona winds.

This evolving pattern will support a renewed increase in shower coverage and intensity from late week into the weekend, with model consensus suggesting an additional several inches of rainfall possible over portions of the state during this period. While this next system does not currently appear to be as intense as the recent event, it will impact an already highly saturated environment.

Given the antecedent conditions, including elevated streams and saturated soils, even moderate rainfall rates may quickly lead to runoff issues. The threat for flash flooding will remain elevated statewide through the week, with the potential for more significant impacts returning late in the week into the weekend.

Hawaii’s Marine Environment…as of 442pm Monday:  The gradient will remain rather weak through Wednesday, with light and variable winds prevailing over the waters. A brief period of light to moderate trades will be possible Thursday as a weak ridge builds north of the state, followed by light to moderate S winds on Friday as a new system approaches from the west.

Surf along S shores is trending down as S to SW winds ease. A new long period south swell will then arrive late tonight and Tuesday giving an extended boost to S shore surf through late this week. A moderate short-period W swell associated with the recent kona storm is affecting N and W facing shores, but surf remains below the advisory threshold.

The short-period W swell will lower tonight and Tuesday while a new medium-period NNW swell fills in. This NNW swell could elevate surf to near the advisory threshold Tuesday night and Wednesday. The swell then shifts more N and lowers Thursday into the weekend. Surf along E facing shores will remain well below normal through late week, as trades over and upstream of the islands remain disrupted.

Interesting:  Here’s Why you Need to Charge your EV More Often in the Cold

When the temperature drops to -20°C, we electric car owners quickly notice it on our wallets. But is it just a matter of driving with the heat on full blast? And what can we do to save the battery as much as possible?

You charged your car to 80 percent last night, and this morning it’s at 78 percent. The fast charger, which usually takes half an hour, now takes almost two hours. And on the way to work, you notice that the battery percentage is dropping faster than normal.

We spoke to senior researcher and battery expert, Fride Vullum-Bruer, to gain a little more insight into why batteries behave the way they do, and what we as users can do to protect the battery as much as possible in the cold.

Yes, you have to charge your EV more often when the temperature drops. But with simple adjustments, you can use your electric vehicle in a predictable and safe way, even when the temperature drops to 20 below.
