Researchers are unable to come up with any answers as to what the “milky rain” falling over parts of Oregon, Washington and Idaho actually is, and all the while, residents of those areas are filling up cups with the substance to see for themselves what it could be.
The rain pouring down over residents in the Pacific Northwest is gross to look at, and while scientists have been unable to determine what it is, there are many theories already being examined.
“There are a whole bunch of theories,” National Weather Service meteorologist Robert Cramp noted. “But the reports are coming in from a limited area. If it is from a cloud of volcanic ash drifting this way, it seems like we would be seeing the milky rain in a larger area.”
One of the most popular theories is that the “milky rain” is a result of recent volcanic eruptions in Russia and Mexico. As Cramp notes, however, the rain would most likely be seen in cities like Seattle and Portland if it were in fact a cloud of volcanic ash.
Authorities is Walla Walla County, Washington recently sent correspondence to residents explaining that the “white stuff” was ash launched into the atmosphere by Volcano Shiveluch in Russia, nearly 4,000 miles away. The National Weather Service, however, says they don’t know where county officials got their information from and are making clear that they still don’t know where the “milky rain” is coming from.
“We have heard a few theories thus far including; volcanic ash from Mexico or Russia, dust picked up from last night's strong winds, or perhaps ash from last year's wildfires over SE Oregon/SW Idaho,” The National Weather Service said in a statement. “We still don't have a definitive answer.”
Researchers are continuing to investigate the mysterious “milky rain” coming down over parts of the Pacific Northwest and say they will update residents as they learn more.
