Leslie made landfall earlier this morning along the Burin Peninsula in Newfoundland. As expected, the really strong winds were on the east side of the storm with Category 1 hurricane-force gusts in the St. John's area. Heavy rainfall was an issue well to the northwest and west of the center.
Also....
1. Looks like a very dry and warm pattern setting up across BC and the Pacific Northwest in the U.S. especially late this week and through all of next week as a large ridge of high pressure builds up along the West Coast. This is obviously bad news for wildfire control.
2. Also next week, as this big ridge strengthens along the West Coast, a stronger, north-to-northwest flow will come down through the Prairies, and we could be seeing a significant cool spell into the Prairies and northern U.S. Plains late next week. This is the type of situation that will lead to widespread freezes and perhaps some snowflakes.
Speaking of snow, snow fell last night at Sunshine Village Ski Area in Banff. Check out the images below from this morning...
