Tropical Storm Cristobal forms near the Yucatan, this is the third named storm of the season. Last year, the third named storm didn't form until August 20. It's the earliest third named storm since record keeping began in 1851 (beating out Colin that formed on June 5, 2016). Current track has it nearing Cat-1 strength by Sunday south of Louisiana, but NOAA says their confidence is very low.
