It’s getting close to that time of year when weather watchers and water managers start wringing their hands and wondering whether it will be a boy or a girl. The boy is none other than El Niño – that Pacific weather pattern characterized by warm ocean temperatures and heavy precipitation. Last year, we heard all about the monster El Niño that would refill California’s reservoirs. But it never actually materialized. Now, the National Weather Service projects a different winter visitor – La Niña. She’s the opposite of her brother – a weather pattern characterized by dry conditions.
