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 Tuesday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear here in Maui County early this morning.  The low temperature at my place was 53.5 degrees.

Hawaii’s Broad Brush Weather Overview:  A high pressure system will remain in place north of the Hawaiian Islands through the weekend, keeping moderate to locally breezy trade winds into the extended range forecast. A disturbance passing through the islands today will briefly increase shower activity through the morning hours.

More stable conditions with limited shower activity returns into Friday. Another upper level disturbance moves over the islands producing a slight increase in shower activity forecast from Friday afternoon through the weekend.

Hawaii’s Weather Details: A trough moving through the islands shows up on this mornings satellite imagery as unstable cloud bands moving through the central and western islands. More stable stratocumulus clouds are filling in behind this trough as the ridge builds over the state, and we return to more stable weather conditions later today. Local radar imagery shows scattered shower bands drifting into the windward and mountain slopes of each island on the trade winds. A few of the strongest showers may bring brief showers to the typically drier leeward areas.

After a locally wet summer morning, expect drier and more stable conditions to develop across the state lasting into Friday, as high pressure will keep a subsidence cap on vertical cloud development. Subtle changes in the island cloud and shower pattern will become less stable from late Friday on into the weekend, as a weak upper level low brings some instability across the island chain. A slight increase in showers are anticipated mainly during the overnight to early morning hours favoring the windward and mountain areas.

Confidence in these shower trends remain moderate at this time, as the strength of the upper low is currently projected to be on the weaker side of the equation. Details will become clearer later this week, as the time period grows closer, and confidence on island by island shower trends improve.

Fire weather:  Trade winds will remain in the moderate to locally breezy range into the upcoming weekend. After a period of higher humidity levels and elevated shower trends this morning, weather conditions will dry out and become more stable into Friday. Another increase in shower trends may develop from Friday afternoon through the weekend, as an upper level disturbance moves over the island chain.

Hawaii’s Marine Environment:  A ridge of high pressure will remain far north of the state throughout the week. Trades should gradually strengthen. A Small Craft Advisory (SCA) is in effect for the typical windy areas around Maui County and the Big Island. Fresh to locally strong trades will likely persist through most of the week, although we could see winds drop below SCA criteria as a weak trough develops over the western end of the state into the weekend.

Surf along south facing shores should see a small boost over the next few days, due to a pair of south and south-southeast swells. A long-period south swell should peak near summer averages. As this swell declines a reinforcing swell from the south- southeast should fill in later today into Wednesday. This should maintain surf heights through the middle of the week. Surf should gradually decline Thursday into Friday, but another small increase is expected into the weekend, as a new long-period southwest swell arrives from the Tasman Sea.

Surf along east facing shores will continue to remain rough and choppy with surf heights getting a slight increase as the trades strengthen. Surf along north facing shores will continue to decline through Wednesday.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclone

Caribbean Sea:  There are no active tropical cyclone

Tropical cyclone formation is not expected during the next 7-days.

Gulf of America:  There are no active tropical cyclone

East of the Florida Peninsula into the Northeastern Gulf:

Invest 93L

East of the Florida Peninsula into the Northeastern Gulf (AL93): Satellite and radar data indicate that the shower and thunderstorm activity associated with the low pressure located just offshore of the east coast of Florida remains disorganized.

This system is forecast to move westward across the Florida Peninsula today and then reach the northeastern Gulf by Wednesday. Environmental conditions appear generally favorable for additional development, and a tropical depression could form while the system moves across the northeastern and north-central Gulf.

Regardless of development, heavy rainfall could produce localized flash flooding over portions of Florida through mid-week. Heavy rainfall could also cause flash flooding for portions of the north-central Gulf Coast during the middle to latter portions of this week

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…medium…40 percent

Interesting:  Time to Throw Away the Plastics in Your Kitchen?



Plastic containers and utensils are staples in many kitchens—but could they be affecting your health?

Plastics, often seen as a single material, are actually made from many different polymers, each with a unique chemical makeup. They contain different chemical additives like dyes, plasticizers, and flame retardants. As these plastics interact with microbes and environmental chemicals, the risk to human health becomes more complex.

University of Rochester researchers are at the forefront of efforts to understand the complex role that plastics play in human health. They include Katrina Korfmacher, the codirector of the Lake Ontario MicroPlastics Center (LOMP) and a professor of environmental medicine, a collaboration between the University and Rochester Institute of Technology (RIT), and Jane van Dis, an assistant professor of obstetrics and gynecology at the Medical Center.
