The French Toast Alert System — developed by Universal Hub to tell you when it’s time to buy milk, bread and eggs in advance of a winter storm — has been raised to “Severe,” its highest level.

This is it, people. A nor’easter is coming.

From the National Weather Service, 11:10 p.m.:

A DANGEROUS WINTER STORM WILL BE AFFECTING SOUTHERN NEW ENGLAND SUNDAY AFTERNOON THROUGH MONDAY. LOW PRESSURE WILL INTENSIFY OFF THE NORTH CAROLINA COAST SUNDAY MORNING THEN BECOME A VERY INTENSE STORM AS IT PASSES JUST SOUTHEAST OF NANTUCKET MONDAY MORNING. THE LOW SHOULD PULL AWAY LATER MONDAY BUT VERY WINDY CONDITIONS WILL CONTINUE INTO TUESDAY. A MODERATING TEMPERATURE TREND WILL DEVELOP DURING MIDWEEK AS HIGH PRESSURE BUILDS ACROSS THE EASTERN SEABOARD.

Forecasters expect a dumping of 15 to 20 inches and sustained wind gusts of 35 miles per hour. Stay off the roads.

Oh yeah, don’t forget to shovel.
