Hawaii’s MountainsHere’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (nearly 13,800 feet high) on the Big Island of Hawaii. This webcam is 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.

~~~ Hawaii Weather Narrative ~~~

 

Broad Brush Overview: A mid-summer trade wind weather pattern will continue through the week. Clouds and passing showers will favor windward and mountain areas, although will be limited through mid-week. The trade winds will ease slightly today through Wednesday, before picking up some later in the week…carrying off and on showers our way.

Moderately strong high pressure systems are located to our north, which are keeping breezy trade winds in place…with no end in sight. Satellite imagery shows partly cloudy skies, along with high cirrus clouds moving across island skies too. Radar shows a few light showers moving into the windward areas, with dry conditions prevailing leeward.

As far as tropical cyclone activity goes here in the Central Pacific: there isn’t expected to be any change…from the quiet reality we now have. Some of the models are showing a tropical disturbance forming well to the east-southeast of the islands around August 9th (Wednesday)…and then moving by to the south of the islands around August 13th (Sunday). The latest model runs are starting to back off on this idea now, let’s give it another day.

Here’s a wind profile of the Pacific Ocean – Closer view of the islands / Here’s the vog forecast animation / Here’s the latest weather map

Marine environment details: Trade winds will last through the week. The strength of the trades start off moderate to locally strong, then will ease to moderate through mid-week. A boost in the trades will take place Thursday, as a new surface high moves into place well north of Kauai…staying there into the weekend. As a result, the trades will rebound to moderate to strong by Thursday night, and continue into the weekend. The Small Craft Advisory (SCA), currently in effect for the Alenuihaha Channel, will likely be lowered late this afternoon. A new SCA will likely be issued about Wednesday night, and the coverage may extend beyond the typical waters around Maui County and south of the Big Island.

No significant swells are expected during the week. The locally generated trade wind swell will drop off slightly Tuesday, then increase Friday, in response to the new round of strong trades. Choppy waters and rough seas will return as well.

A new south swell will arrive this coming weekend.

World-wide tropical cyclone activity


https://icons.wxug.com/data/images/sst_basin/gl_sst_mm.gif


>>> Atlantic Ocean: No active tropical cyclone

A trough of low pressure located about 800 miles east of the Lesser Antilles continues to produce an area of disorganized showers and thunderstorms. Development of this system is not expected during the next few days due to unfavorable environmental conditions. However, some development of this system is possible this weekend while the system moves generally west-northwestward at about 15 mph over the western Atlantic.

This disturbance is being referred to as Invest 99L, here’s a satellite image…along with what the computer models are showing.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…30 percent

>>> Caribbean Sea: 

Tropical Storm 07L (Franklin) remains active, here’s a graphical track map, a satellite image…and what the computer models are showing.

>>> Gulf of Mexico: No active tropical cyclone

>>> Eastern Pacific: No active tropical cyclone

No tropical cyclones are expected during the next 5-days

An area of low pressure could form a couple of hundred miles south of the southern tip of the Baja California peninsula late this week in association with the remnants of Atlantic Tropical Storm Franklin after it moves across southern Mexico. Environmental conditions could be conducive for some re-development of the system while it moves toward the west-northwest or northwest near 10 mph.

Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

Death Valley Breaks Record for Hottest Month Ever in the US
— July temperatures in Death Valley have incinerated previous records.

With an average daily high temperature of 107.4 degrees Fahrenheit, July was the valley’s hottest month on record, blazing through the former record of 107.2 degrees F set in 1917.

Temperatures in Death Valley in July blazed into the record books not only as the hottest month in the desert valley in eastern California but also as the hottest month ever recorded in the United States, according to NWS Las Vegas.

During July, temperatures were at their lowest at around 5 a.m. local time, averaging about 95 degrees F (35 degrees C), Death Valley National Park representatives wrote in a Facebook post on August 3.

“This is an extreme place to live and visit in the summer, especially this past month,” they said.

A photo shared in the post showed a National Park Service (NPS) official posing next to the Furnace Creek Visitor Center in the park, leaning against a sign displaying a local temperature of 124 degrees F.

Death Valley’s highest temperatures during July were 127 degrees F on July 7; 126 degrees F on July 8; and 125 degrees F on July 31, according to daily temperature reports compiled by the National Weather Service, The Washington Post reported.

A combination of geological factors — including its low elevation and the presence of surrounding mountains that block cooling moisture — trap and fuel the baking heat that develops during summer in Death Valley.

Death Valley holds the record for the highest temperature ever recorded on Earth — 134 degrees F on July 10, 2013, which was part of a five-day heat wave during which temperatures hovered at 129 degrees F or more, the NPS reported.

Death Valley isn’t the only place where things are heating up — global average temperatures have been on the rise for years. 2016 was the hottest year on record for the third consecutive year, and a forecast for August, September and October 2017 predicts more warmer-than-average temperatures in the Northern Hemisphere, according to a report released by the National Oceanic and Atmospheric Administration.
