The National Hurricane Center continues to track the path of Tropical Storm Erin as it heads west, but the storm's potential impact on the Caribbean remains uncertain. The high in Phoenix reached 109 today, far away from the record that was set in 2012.

Tropical Storm Erin is forecast to strengthen into the first hurricane of the Atlantic season by Saturday morning and then become a major Category 3 hurricane by Sunday morning as it passes north of Puerto Rico. But as of now, Erin is not expected to pose a direct threat to the U.S.
