— The damage from two storms that caused major flooding and heavy rain across much of Mexico could top 75 billion pesos ($5.76 billion), the highest ever cost from a natural disaster in the country, Mexico’s insurers’ association said on Thursday. The storms, which struck Mexico’s Gulf and Pacific coasts simultaneously two weeks ago, have killed at least 145 people and damaged bridges, roads and crops across the country. Recaredo Arias, chief executive of the Mexican Association of Insurance Institutions, said the 75 billion peso figure was based on government estimates and that the insurers’ association agreed with them. The government has still to publish its own official estimates.
