The northern lights are expected to dance across Alaska and the rest of the U.S. Tuesday night, according to the University of Alaska Fairbanks' Geophysical Institute.
"Weather permitting, highly active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Iqaluit to Vancouver, Helena, Minneapolis, Milwaukee, Bay City, Toronto, Montpelier and Charlottetown, and visible low on the horizon from Salem, Boise, Cheyenne, Lincoln, Indianapolis and Annapolis," the Geophysical Institute wrote.
The aurora intensity is rated on a scale of 0 to 9. On Monday, initial reports of the forecast were rated at a seven, but by Tuesday the intensity level had been downgraded to a six, which is still high -- even for Alaska.
But what are the odds of actually seeing the aurora Tuesday night? In Alaska, your odds are best in the Southcentral region -- but your chances will dwindle away around midnight, when more clouds roll in.
"Your chances are 50/50," National Weather Service meteorologist Dan Peterson said. "There is a dry slot and then more clouds and fog," Peterson said. He added that your best chance is to see the northern lights is between "now and midnight."
The NWS forecast mostly cloudy skies for much of the Interior, western, southwest, southeast and the North Slope regions of the state.
