The post-tropical cyclone is moving toward the north-northeast near

Cristobal tracks into Ontario, Canada.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Little change in strength is forecast during the next 48 hours. 

The estimated minimum central pressure is 983 mb (29.03 inches).

Sporadic heavy rain is possible today across the Great Lakes,
along and ahead of a cold front associated with extratropical

Lakes region, with the greatest chances in parts of Michigan, 
Indiana and Ohio.
