Update: The storm watch has now been updated to a winter storm warning (Monday, Feb. 11, 2019, 4:50 p.m.)
Environment Canada has issued a winter storm watch for Kingston, Odessa, Frontenac Islands, Napanee, Consecon, Picton and Sandbanks Park, predicting a winter storm with significant snow, freezing rain, and strong winds on Tuesday.
Environment Canada says a low pressure system brewing over the Southern Plains States may intensify into a winter storm as it tracks over Southern Ontario on Tuesday. Snow is expected to arrive Tuesday morning and continue into Wednesday. The snow may mix with ice pellets for a few hours before changing back to snow by Tuesday night, and there is also a risk of freezing rain. Snow may taper off to flurries late on Wednesday.
How much snow and ice pellets a region receives will depend on the exact track of the low. Total snowfall and ice pellet amounts of 25 to 35 cm are possible.
Strong and gusty easterly winds as high as 80km/h may cause low visibility in blowing snow, and this weather system may have a significant impact on travel.
