An ' atmospheric river ' storm approaching California is expected to soak most Bay Area cities Wednesday with 1 to 3 inches of rain and blanket the The heaviest rains should arrive as part of a cold front Wednesday afternoon through Thursday morning, bringing wind gusts of 50 to 70 mph in

An atmospheric river is expected to impact the Bay Area beginning Tuesday night and deliver 1 to 3 But over the weekend the forecast has shifted, and the storm is now expected to have a greater Along with the rains , sustained winds of 30 to 40 mph are expected Wednesday with gusts of 60 to

20,000 homes feared lost in Australia floods as crocodiles and snakes wash up

20,000 homes feared lost in Australia floods as crocodiles and snakes wash up Devastating flooding in northeast Australia has forced thousands of people from their homes and brought snakes and crocodiles onto the streets as authorities warn of strong winds and more rain on the way. Much of the city of Townsville in Queensland state is flooded, with residents left without power and some compelled to seek safety on the roofs of their homes, according to CNN affiliate 7 News. Intense rain on Sunday forced authorities to open the floodgates on the Ross River Dam to relieve pressure, releasing around 1,900 cubic meters of water per second downriver.

On the coast, San Francisco recorded 50 mph gusts and Oakland 48 mph , the service said. Such atmospheric river drenchings in California are rare but also normal and necessary, the National Fort Bragg in California will get hit from two sides, with up to 5 inches of rainfall by late Thursday

Heavy rain could become an additional hazard alongside gusts of 50 -60 mph , possibly reaching up to 70 mph across exposed coastlines. She added: "A deep area of low pressure will bring heavy rain and strong winds across northern and western regions overnight tonight and through tomorrow

The weather phenomenon, a narrow corridor carrying water vapor from the tropics near Hawaii onto California shores, is expected to dump up to 2 inches of rain in San Francisco and Oakland. Some of the North Bay and South Bay mountains could see up to 4 inches of rain, said Spencer Tangen, a National Weather Service meteorologist.

“All the rain we’re going to get on top of that is just going to lead to worsening flood problems,” Tangen said. “There are higher potentials for landslides and debris flows than we saw before all this rain.”

The heaviest rain is expected to arrive Wednesday morning during commute hours, forecasters said. The National Weather Service issued a flash flood watch for the Bay Area from 10 p.m. Tuesday to 10 a.m. Thursday.

Scientists Develop Category System To Warn Residents About Strong Storms

Scientists Develop Category System To Warn Residents About Strong Storms Meteorologists have created a new scale to track the strong winter storms that slam the west coast. The new system could help give more people warning and ranks some of our past storms. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); Northern California is no stranger to strong storms that cause flooding, levee breaks, and mudslides. In the past, they’ve been known as a pineapple express, and more recently they’ve been dubbed atmospheric rivers.

Atmospheric river storms are drought busters in California , dumping huge amounts of rain in narrow corridors within short periods of time. The storm is likely to cause major traffic delays across Southern California , and may bring air travel to a standstill for several hours as winds gust to 50 miles per

Heavy rain could cause flooding and debris flows in California into this weekend as an atmospheric river event takes aim. A storm system tapping into an atmospheric river of moisture will pummel California through early weekend, wringing out heavy rain that could potentially cause flooding

Accompanying the storm is a round of strong winds that could uproot trees and knock down power lines, especially given recent repeated rainstorms that have saturated the ground. Winds along the coast on Wednesday afternoon could reach 30 to 35 mph, with gusts up to 50 mph. Higher elevations may see wind gusts up to 70 mph, Tangen said.

Last week’s snow in the East Bay hills, the Santa Cruz mountains and other spots will likely melt with the arrival of the atmospheric river, Tangen said, and that could contribute to rising river levels.

“This warmer weather is going to melt that snow and that’ll add a little bit to the runoff,” Tangen said.

Warmer temperatures are also expected to prevail in the Bay Area with the tropical moisture, with highs bouncing up to the middle to upper 50s midweek.

Monster storm pummels California, prompting evacuations amid mudslides and flooding.
A fierce winter storm packed with subtropical moisture continued its destructive path across California on Thursday, triggering widespread flooding that prompted evacuations and unleashing a mudslide that sent one home sliding into another in Marin County. Southern Marin fire officials said the mudslide dislodged the home from its foundation and pushed it down a hill before it slammed into another residence shortly before 3 a.m. Rescuers pulled
