LA NINA'S BREWING, FORECASTERS WARN
Forecasters warned Tuesday that a La Nina weather pattern - the nasty flip side of El Nino - is brewing, bringing with it the threat of more hurricanes for the Atlantic.
Officials at the National Oceanic and Atmospheric Administration announced the official end of a brief and mild El Nino that started last year. That El Nino was credited with partially shutting down last summer's Atlantic hurricane activity in the midst of what was supposed to be a busy season.
"We're seeing a shift to the La Nina, it's clearly in the data," NOAA Administrator Conrad Lautenbacher said. La Nina, a cooling of the mid-Pacific equatorial region, has not officially begun because it's a process with several months with specific temperature thresholds, but the trend is obvious based on satellite and ocean measurement data, he said.
"It certainly won't be welcome news for those living off the coast right now," Lautenbacher said. But he said that doesn't mean Atlantic seaboard residents should sell their homes.
Forecasters don't know how strong this La Nina will be. However, it typically means more hurricanes in the Atlantic, fewer in the Pacific, less rain and more heat for the already drought-stricken South, and a milder spring and summer in the north, Lautenbacher said. The central plains of the United States tend be drier in the fall during La Ninas, while the Pacific Northwest tends to be wetter in the late fall and early winter.
Of special concern is west Texas which is already in a long-term drought, which during a La Nina will likely get worse, Lautenbacher said.
