Federal Climate Scientists say La Nina conditions that are responsible for active hurricanes are weakening. Federal Climate Scientists say La Nina conditions that are responsible for active hurricanes are weakening. State Climatologist Barry Keim says there's been a La Nina in place for about a year now and it's expected to disappear before the start of hurricane season. Keim says this is good news for Louisiana because we typically get more hurricanes during La Nina's. He says this doesn't mean we won't get hit with a hurricane this year. Keim says that despite this weakening, we can still expect to have La Nina type conditions throughout the spring.
