Groundhog predicts six more weeks of winter

PUNXSUTAWNEY, Pennsylvania (Reuters) - An American groundhog delivered his annual weather prediction on Tuesday, declaring that there will be six more weeks of winter after seeing his shadow.

U.S.  |  Lifestyle
Dubbed "Punxsutawney Phil," the rodent made his forecast in front of some 12,000 people who came from as far as Chile and the Netherlands and braved a chilly 18 degrees Fahrenheit (-8 degrees Celsius) to see the more than century-old tradition.

If Phil does not see his shadow when he emerges from his burrow, which is a box set into a tree stump near the western Pennsylvania town of Punxsutawney, spring is said to be just around the corner.

Several other Groundhog Day celebrations are held around the United States. A high-profile rival delivered a different prediction on Tuesday, with local media reporting that New York City's "Staten Island Chuck" did not see his shadow.
