An abnormally warm climate in Alaska and an abnormally hot ocean puddle in the Pacific known as "the spot" could wreak havoc on the American climate
- A period of high pressure persists over the Gulf of Alaska.
- It's causing an abnormally warm weather and a bag of warm ocean water
- Previous Blobs have contributed to a California drought in 2013-2015
The warm climate of Alaska is the result of the "bubble", a period of high pressure on the coast of the state.
This dome of warm air has stunted the progression of autumn and has seen the state cling to the remnants of summer.
Unusual weather patterns have spread beyond the air temperature and have spread to the ocean, with an area of warm water in the generally frigid waters of the northern Pacific.

The warm climate of Alaska is the result of the "bubble", a period of high pressure on the coast of the state. The previous iterations of the bubble have appeared and had significant impacts on the lower 48.
Scientists are not sure how long the bubble will remain and the consequences it can have on the climate for the 48 contiguous states.

Previous experience says that the stain causes unusually warm and dry conditions in the west and cold and stormy conditions in the east.
This is a result of the high pressure zone in the Gulf of Alaska that causes the jet stream to rise above the spot.
A high-pressure wall gathers around the northwestern states and brings a warm climate while blocking storms.
It is believed that the California drought of 2013-2015 was partly caused by one of the blob's predecessors.

The 2015 Seattle was also the hottest in history and was also attributed to the blob.
The National Weather Service on Thursday predicted a winter warmer than normal for three-quarters of the north and west of the nation.
The greatest chance of warmer than normal weather in winter is in Alaska, the Pacific Northwest, Montana, northern Wyoming and western North Dakota.
& # 39; How long will BLOB Jr. last? At least as long as we have persistent high pressure over the North Pacific, "Cliff Mass, professor of atmospheric science at the University of Washington, wrote in a blog post.
Professor Mass added: "It seems that things are evolving into a pattern with less pressure on the high seas, so the BLOB should weaken.
THE NOAA 2019 WINTER PROGNOSIS
- Warmer than normal conditions are anticipated in much of the north and west of the US. UU., Most likely in Alaska and from the Pacific Northwest to the Northern Plains.
- The Southeast, the Tennessee Valley, the Ohio Valley, and the Mid-Atlantic have all the same opportunities for temperatures below, below, or above average.
- No part of the USA UU It is favored for having temperatures below the average.
Northern Florida and southern Georgia have the highest chance of above-average precipitation this winter
- The wetter conditions than the average are favored throughout the southern EE. UU And to the middle Atlantic. Northern Florida and southern Georgia have the highest chances of above average rainfall this winter.
- Drier than average conditions are more likely in northern parts of the Rocky Mountains and Northern Plains, as well as in the Great Lakes and northern Ohio Valley.
- Drought conditions are likely to persist in parts of southwestern, southern California, the Great Central Basin, the Central Rocky Mountains, the Northern Plains, and parts of the interior Pacific Northwest.
- It is anticipated that drought conditions will improve in areas throughout Arizona and New Mexico, the southern sections of Utah and Colorado, the Pacific Northwest and the Central Plains.
