ALBANY, N.Y. (AP) -- Rain? Snow? Flooding? All of the above?It's all depends where you are in upstate New York as a Nor'easter bears in on the New York-New England coast this weekend.The National Weather Service had a full menu of winter storm advisories, watches and warnings. The most serious was in place Saturday from Albany to Buffalo, with as much as 20 inches of snow possible at higher elevations in the Adirondacks and several inches of rain in the Hudson Valley by the time the storm passes late Monday and Tuesday."I don't think at any point in time there'll be more than a couple of inches of snow on the ground," weather service meteorologist George Maglaras said of the Capital Region and south into the Hudson Valley.A winter storm watch for that region was lifted Saturday and Maglaras said forecasts call for the equivalent of 1 1/2 to 3 inches of rain starting Sunday.But flood and winter storm watches remained in place for the Catskills and a winter weather warning predicted anywhere from 10 to 20 inches of snow in the Adirondacks. A warning was also in place for the snowy counties east of Lake Ontario, where the forecast called for 12 to 18 inches of snow.South of the lake, a winter weather advisory carries the possibility of up to a foot of snow around Rochester and a watch remained in place in the Southern Tier around Binghamton and Elmira.Maglaras said the weather service's latest information shows temperatures will be a little milder than expected earlier, accounting for the increased likelihood the storm will dump rain rather than snow at lower elevations.Albany International Airport spokesman Doug Myers said airlines are beginning to look at how they will stage planes in and out of the airport Sunday night and Monday morning.In New York City and on Long Island, city and state officials were preparing for the possibility of coastal flooding and high winds and Gov. Eliot Spitzer alerted the National Guard to be ready to help with emergency work. Some local communities readied sandbags, cleaned drains and made other preparations.
