WFMZ's free new weather app sponsored by St. Luke's University Health Network provides hourly weather details, 10-day extended forecasts, weather maps and alerts.

"At the tip of their fingers, Lehigh Valley residents now have access to accurate, up-to-date weather information anywhere at any time," said WFMZ General Manager Barry Fisher. "We are grateful to St. Luke's for partnering with us to make this happen."

The hourly forecast details the weather conditions for a 24-hour period. It includes precipitation, wind speeds and temperatures. The 10-day forecast lists high and low temperatures.

The free interactive map features include selectable Future Cast Radar, Radar, Storm Track Direction, Wind Speed, Snow Cover and many other tools.

iPhone and Andriod App users will also receive National Weather Service severe weather alert notifications.

In addition, the map function enables the user to change the forecast to any city in the United States.
