HARTFORD, Conn. — Storm Isaias’ path of destruction through much of the East Coast could easily push insurance claims for property damage into the billions of dollars, but it may only be the beginning as forecasters predict twice as many named storms in the 2020 hurricane season as usual. The prospect of more turbulent weather — and damage — possibly coming to some areas comes on top of worries about the future of the COVID-19 pandemic. “We are looking at an extremely active season and perhaps one that is on par with 2005,” Mark Friedlander, a spokesman for the Insurance Information Institute, said, pointing to the most active year on record and the one in which Katrina struck New Orleans.
