Hurricanes need four conditions to form:

* low air pressure

* warm temperatures

* moist ocean air

* tropical winds (near the equator).

Hurricanes form in the tropics, over warm ocean water (over 80ºF or 27ºC) and at latitudes between 8° and 20°.

They form mostly from June through November, or during the hurricane season. These powerful storms are fuelled by the heat energy that is released when water vapour condenses and turns into liquid water or rain).

A hurricane goes through many stages as it develops:

1. It starts as a tropical wave, a westward-moving area of low air pressure.

2. As the warm, moist air over the ocean rises in the low air pressure area, cold air from above replaces it. This produces strong gusty winds, heavy rain and thunderclouds that is called a tropical disturbance.

3. As the air pressure drops and there are sustained winds up to 38 miles per hour, it is called a tropical depression.

4. When the cyclonic winds have sustained speeds from 39 to 73 miles per hour, it is called a tropical storm (storms are given names when they begin to have winds of this speed).

5. The storm becomes a hurricane when there are sustained winds of over 73 miles per hour.

As for the end of a storm, when a hurricane travels over land or cold water, its energy source (warm water) is gone and the storm weakens, quickly dying.

If that Low were in the gulf of Mexico there would be all kinds of warnings going out right now... but being AK that's just another cold windy day up there

According to this, not weird at all. And, hey, I'm in NC too.

Some Historical Weather Events in the Pacific Northwest
These systems can match a Category 3 hurricane in both minimum central pressures and sustained wind speeds. Such storms have a reach far beyond that of a typical hurricane: they can throw a cold rain into the Alaska Panhandle while at the same time pummel the San Francisco Bay Area with a warm, saturated gale. These tempests are killers, and can cause damage into the hundreds of millions, even billions. The focus of these web pages is on extratropical cyclones; though, as weather and climate contain varied and diverse phenomena, other types of events are also examined.


Lots of information and storm data on midlatitude cyclones

Correct me if I am wrong but didnt someone post a thread concerning changes in the sun in the last few days. I am totally unorganized since I am right handed(according to another thread) and can never verify anything or remember who said what about where and when it will or will not happen....
