‘Pineapple Express’ And Bomb Cyclone To Wallop California
‘Pineapple Express’ And Bomb Cyclone To Wallop California
A moisture conveyor belt of atmospheric rivers has unleashed near-record rainfall across the West Coast. Another, perhaps, more powerful atmospheric river and bomb cyclone are set to target California on Wednesday and Thursday, continuing ten days of heavy rains and snow for higher altitudes.
The National Weather Service office in the Bay Area warned about the imminent storm, calling it a “truly … brutal system … that needs to be taken seriously.”
“To put it simply, this will likely be one of the most impactful systems on a widespread scale that this meteorologist has seen in a long while,” an NWS meteorologist in San Francisco, adding, “the impacts will include widespread flooding, roads washing out, hillside collapsing, trees down (potentially full groves), widespread power outages, immediate disruption to commerce and the worst of all, likely loss of human life.”
The developing atmospheric river formed near Hawaii and, by Wednesday morning, will spread tropical moisture into California by a low-pressure system. This weather phenomenon is known as the “Pineapple Express.”
“Basically, an (atmospheric river) is a river in the sky of water vapor, and when it hits the mountains, (the moisture) is forced up over the mountains.
“That upward motion causes clouds and precipitation to form, and the faster the flow of air and water vapor is hitting the mountains, the faster the rain is falling, so you get more and more rain with the stronger ARs hitting the mountains,” Marty Ralph, Director of the Center for Western Weather and Water Extremes, told FOX Weather.
The heaviest rainbands are forecasted over parts of California Wednesday afternoon and evening into Thursday morning. NWS has already posted flood alerts across the Golden State.
Another 2-3 inches could be expected across the San Francisco area. Even the Los Angeles metro area could see 1-3 inches.

This Flu Season Begins the Risk of a Pandemic 2018-2019
A possible new pandemic is forming from a deadly strain of flu emerging from Australia and will be headed to the UK as the normal flow of travels would take it. Britain will perhaps be hit with the worst flu season in 50 years. Already, there are about 170,000 cases of flu reported in Australia which is more than double this season than usual.
The strain of flu is called H3N2, and the number of flu deaths in Australia over winter has not yet been released, but it’s thought to be the worst in many years. The last major flu epidemic was in the 1968 pandemic which began in Hong Kong killing more than a million people worldwide. Flu pandemics have been linked to fluctuations in climate, and new research connects the world’s four most recent pandemics to the cyclical cooling of the Pacific Ocean near the equator.
The cyclical research correlating everything reveals that the four flu outbreaks that swept the world in the past 100 years all followed periods of global cooling. These were in 1918, 1957, 1968 and 2009 (in this last instance, the H1N1 “swine flu”). When sea-surface temperatures sank abnormally low, this correlates to large flu pandemics. This cooling is associated with La Niña, a phase in a larger climate pattern. La Niña is the cool counterpart to El Niño, which is marked by unusually warm temperatures in the equatorial Pacific. It is now clear that both events alter weather patterns around the globe.
While the typical Transverse Wave cycle event would be every 22.75 years, but the Longitudinal Wave structure simultaneously exists and the complexity of these wave points to this season as turning up the risk factors for a pandemic flu season in 2018 and 2019.
