It's still way too early to worry about a U.S. landfall, but Hurricane Irma is becoming a monster.
The storm packs 115-mile-per-hour winds, and the National Hurricane Center says that in four or five days, it could peak at 140 miles per hour. The forecast track still has it heading for the Leeward Islands, but from there it could continue west into the Caribbean or turn northward to the U.S. -- or even out to sea.
And another tropical wave has emerged from the African coast, with a 50 percent chance of becoming a tropical cyclone in the next five days.
