Damage from Patricia, the strongest hurricane ever measured in the Western Hemisphere, may cost the U.S. billions from floods, even after the storm spared the largest cities in Mexico. Flooding in Texas may lead to more than $3 billion in losses, though it’s too early to project the extent of damages, according to Chuck Watson, director of research and development at Kinetic Analysis Corp. Losses in Mexico are likely to be less than $2 billion, he said.
