(CNN) -- Forecasters had their eyes on two tropical storms early Saturday -- one in the Pacific and one in the Atlantic.
Tropical Storm Estelle intensified Friday evening with maximum sustained winds of up to 50 mph. It's about 220 miles southwest of Manzanillo, along the Pacific coast of Mexico.
Estelle is moving away from land toward the west-northwest at about 10 mph. It may strengthen over the next day and then gradually weaken as it continues north-northwest into cooler water next week.
The storm is not posing any real threat to land, forecasters said.
Tropical Storm Colin was a little disorganized with maximum sustained winds of about 45 mph.
Colin is about 245 miles south-southwest of Bermuda and moving north at 5 mph. Forecasters say it may strengthen, and is expected to pass near or over Bermuda Saturday night.
A tropical storm warning is in effect for Bermuda. Forecasters expect 2 to 4 inches of rain, which might cause coastal flooding and battering waves along the beaches facing south.
Colin is not expected to land in the United States. Once it gets past Bermuda, it could work its way early next week near the provinces of Atlantic Canada, particularly Newfoundland.
