*******OT********* SCIENTISTS: RADAR IMAGE SHOWS THINNING OF EL NINO IN PACIFIC Futures World News - February 20, 1998 17:29 WEATHER FOOD ENERGY GRAIN MEAT V%FWN P%FWN San Francisco-Feb. 20-FWN/UPI--DRENCHED CALIFORNIANS today are finally getting some hopeful news--the massive pool of warm Pacific waters that's been blamed for weeks of flooding, mudslides and other devastation appears to be receding. But scientists caution the so-called El Nino is historically full of surprises. And even if the change that's just beginning near the South American coast continues, its weather effects in California won't be felt for many weeks. Researchers at the Jet Propulsion Laboratory in Pasadena, Calif., said the most recent satellite image shows a thinning of the gargantuan pool of warm water in the tropical Pacific. The shift indicates the sea level is slowly beginning to return to a more normal state along the equator. The oceanographers said the area and volume of El Nino that is affecting global weather patterns remain exceptionally large, but the pool of warm water has thinned along the equator and near the coast of South America. That means the warm water is not as deep as it was a few months ago. This, according to the experts, is a classic pattern, typical of a mature El Nino condition they would expect to see during the ocean's gradual transition back to normal. The sea surface temperatures are still well above normal throughout the tropical Pacific and are expected to remain that way into April and May. The scientists said the weather impact is expected to continue through the spring, but, at least, the return to less severe conditions has begun. The news comes on a rare day of sunshine in water- logged California, which is due for another major Pacific storm tonight. In the latest in a series of winter salvos, the National Weather Service forecasts rain on the Northern California coast sometime after nightfall, with at least one inch in the valleys, up to three inches in the Sierra Nevada foothills, and as much as two feet of snow in the mountains. The storms have been blamed for 10 deaths and nearly $300 million in damages in Northern California alone. San Francisco has received 34.99 inches of rain since July 1, more than double the normal amount of 14.5 inches for the season to date. Thursday, downtown San Francisco broke a 120-year-old record for the wettest February, having been soaked with 12.58 inches of rain. That compares to 12.52 inches that fell in February of 1878. Flood control workers are shoring up soggy levees in the Sacramento-San Joaquin River Delta and along the cresting Russian River in Sonoma County, north of San Francisco. The California Conservation Corps dispatched three crews to lay sandbags along the Petaluma River in Sonoma County, where scores of people were evacuated Thursday. Residents of 140 houses in Rio Nido to the east were evacuated earlier, and are still out because of the threat of mudslides.
