TROPICS: Irma Gathering Steam

Harvey has been downgraded to a tropical depression, but we can't let down our guards. Tropical Storm Irma is gathering steam.

Irma is far out in the Atlantic, but the National Hurricane Center predicts that it will reach major hurricane strength in a few days and that its track will take it into the Caribbean Sea. Beyond that, it's too early to tell whether the storm will head for the Gulf of Mexico, turn up the East Coast or simply fizzle out.

In the Pacific, Tropical Storm Lidia is headed for the Baja Peninsula, but forecasters say because of interaction with land, it's unlikely to strengthen much.
