LOS ANGELES (KABC) -- An atmospheric river is arriving in Southern California for Christmas week, bringing four days of heavy rain with the possibility of flash flooding and a drop in temperatures.

The very large atmospheric river -- nicknamed the "Pineapple Express" since it's coming from Hawaii -- is set to arrive on Tuesday afternoon, with rain picking up Tuesday night into Wednesday.

A Flood Watch is in place for most of the greater Los Angeles area starting Tuesday at 4 p.m. through Friday at 4 p.m., with hourly rainfall rates of 0.75 inches to 1.25 inches an hour.

Moderate-to-heavy rain with brief downpours is expected. Some communities could see up to 10 inches of rain over the next several days.

What kind of impacts and damage do different amounts of ice cause?​

"Nuisance"

  • A nuisance ice event is usually one of 1/4 inch or less of ice accumulation.
  • Even though these lighter accumulations are considered nuisance, travel can be extremely dangerous even with a light glazing.
"Disruptive"

  • A disruptive ice storm is typically one of 1/4 to 1/2 inch of ice accumulation.
  • This amount of ice starts to damage trees and power lines.
"Crippling"

  • Wide spread accumulations of over 1/2 inch.
  • With wide spread ice accumulations of over 1/2 inch, there is severe tree damage and power outages may last for days.
  • The most devastating storms contain ice accumulations of an inch or more.

Happy Valley will end up shut off from the world. Above them, Top of the World, folks will be stuck for days.

And a former co-worker will be out there on his tractor with a thermos of coffee, getting $100 for each fool trying to get in or out.

10 of the Worst Ice Storms in U.S. History

Here's a look at 10 of the most damaging, crippling ice storms in U.S. history.
www.wunderground.com


3. Jan. 26-28, 2009 (Arkansas and Kentucky)​

Days of freezing rain led to heavy ice accumulations of 1 to locally more than 2 inches in northern Arkansas and portions of Kentucky in late January 2009.

The heavy icing caused widespread damage to trees, power lines and power poles. Trees fell on homes and cars and blocked roads.

The storm was so damaging that the National Weather Service in both Paducah and Louisville, Kentucky, rated it as the worst weather event of the decade for their respective areas.

Kentucky Gov. Steve Beshear described it as the biggest natural disaster the state had experienced in modern history. Beshear called in National Guard troops to help clear roads and go door-to-door to check on families in the western part of the state, the worst-hit area.

In Arkansas, Mel Coleman, CEO of North Arkansas Electric Cooperative described the scene: "In all of my years I have never seen anything that compares to the damage this storm has caused. I have yet to see a mature tree standing that was not severely damaged. Just opening the door to the outside sounds like a war zone, with the continuous sounds of trees and limbs breaking."

2009 ice storm facts

  • At its peak, 1.3 million customers were without power.
  • It was Kentucky's largest power outage in history at the time, with 609,000 homes and businesses in the dark.
  • Over 200,000 customers lost power in Louisville and it took as long as 10 days to get all customers back online. Area schools were closed for up to a week.
  • Necessities such as food and water were difficult to obtain and lines for gas were hours long.
  • Heavy sleet accumulations across much of southern Illinois and parts of southeastern Missouri caused dozens of roof collapses.
  • At least 30,000 power poles were downed or snapped in Arkansas.
  • More than 145 miles of high-voltage transmission lines were downed in southeastern Missouri.
  • Debris cleanup from the storm lasted into the summer.
  • The storm claimed 24 lives in Kentucky and another 18 in Arkansas from a combination of traffic accidents, hypothermia and carbon monoxide poisoning.
