KEY MESSAGES:
1. There is a danger of life-threatening storm surge for portions of the Upper Texas and Louisiana coastlines where a Storm Surge Warning is in effect. Residents in the warning area should follow advice, including evacuation orders, given by local officials.
2. Damaging and life-threatening hurricane-force winds are expected in portions of southern Louisiana on Wednesday, where a Hurricane Warning is in effect. Preparations to protect life and property should be completed by tonight since tropical storm conditions are expected to begin within this area early Wednesday.

Flash and urban flooding is probable across portions of northeast Mexico and far southern Texas into early Wednesday and the Mid-South Wednesday night into Friday morning.

On this day in weather history:
2003 A Florida couple won $21 million when they bought the winning lottery ticket while shopping for a surge protector after lightning had struck their TV set.
1976 Tropical Storm Kathleen hit San Diego, CA causing widespread flooding and producing 72 mph wind gusts. It is one of the few tropical systems to hit that area.
A nor'easter will continue to cause problems along the Mid-Atlantic coast through midweek, with coastal flooding, beach erosion and dangerous marine conditions. Meanwhile, a storm moving into the West will pull unusually high amounts of moisture into the Southwest and Four Corners, increasing the risk of flash flooding Wednesday and Thursday. That storm will eventually spread rain and thunderstorms into the Plains this weekend, with some locally heavy rainfall possible. Snow is also likely in the higher elevations of the Sierra Nevada and Rockies. Temperatures will run cooler than normal across much of the West, while the Central U.S. stays unusually warm for late October. Another Pacific system will bring precipitation into the Northwest this weekend, and parts of Florida could see repeated rounds of heavy rain.
