SNOW SQUALLS ARE OCCURRING. UNDER THE SNOW SQUALL BANDS,
VISIBILITIES WILL BE SIGNIFICANTLY REDUCED DUE TO THE HEAVY SNOW
COMBINED WITH BLOWING SNOW, AND SNOW WILL QUICKLY ACCUMULATE.

LAKE EFFECT SNOW SQUALLS HAVE DEVELOPED OFF LAKE HURON AND GEORGIAN
BAY AND WILL CONTINUE TONIGHT INTO WEDNESDAY MORNING. SNOWFALL
AMOUNTS IN THE HEAVIEST SNOW SQUALLS COULD REACH 15 CM.

SNOW SQUALLS CAUSE WEATHER CONDITIONS TO VARY
CONSIDERABLY(SEMICOLON) CHANGES FROM CLEAR SKIES TO HEAVY SNOW
WITHIN JUST A FEW KILOMETRES ARE COMMON. VISIBILITY WILL BE SUDDENLY
REDUCED TO NEAR ZERO AT TIMES IN HEAVY SNOW AND BLOWING SNOW. TRAVEL

LOCATIONS.

SNOW SQUALL WARNINGS ARE ISSUED WHEN BANDS OF SNOW FORM THAT PRODUCE
