There's little doubt in my mind now that we're going to see a "hit" from this second Wednesday storm. Widespread power outages may develop Wednesday with northeast to north winds gusting 25 to 35 miles per hour at times. Tides in Boston are forecast around 10.5 feet, Brink said.
Wind gusts from the north-northeast could gusts to 50mph, especially at the coast.
