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.

Erin is expected to reach major hurricane intensity this weekend as it tracks just north of the Caribbean islands, where it could bring rain, gusty winds and high surf. Erin's longer-term future through next week is still somewhat uncertain,
