“There were fears this could be a Katrina-like event,” says Tom Kloza, global head of energy analysis for the Oil Price Information Service. “This is not a Katrina like event.” Refineries in the Houston and Corpus Christi areas shut down before the storm hit Friday to minimize damage. Kloza expects Corpus Christi refineries to reopen within two to three days. Less certain are the effects on the Houston area, where 30 to 40 inches of rain is expected.
