New York Today: Stealth Drought That doesn't sound like much, but it's long overdue. We are in the midst of a drought. Less than half an inch of rain has fallen in the past 6 weeks, when normally 6.35 inches would fall. Last month was the third driest October on record. And so last week, the United States Drought Monitor declared a "moderate drought" for New York City, Long Island and Westchester County. The definition of moderate drought sounds serious. It includes "damage to crops" and "water shortages developing or imminent." But, meteorologists say, we're O.K., partly because we're still coasting off the second wettest June ever. There have been a few more brush fires than usual. But the reservoirs are fine. Still, rain would be good in the coming week, said David Stark, a National Weather Service meteorologist, "Otherwise, it could become worse of a situation." Unfortunately, there is no more rain forecast through Wednesday. So enjoy the raindrops while you may. And pray for more. Here's what else you need to know for Thursday. Whatever rain falls will finish by midafternoon. Still warm: high around 64. Clear and cold tonight. An indoor rink materializes inside Grand Central Terminal's Vanderbilt Hall.

A Maltese falcon is up for auction at Guernsey's on the Upper East Side today. It is not encrusted with jewels beneath its black finish. Nor is it one of the two 47-pound lead statuettes from the 1941 movie known to exist. This one is made of resin and weighs less than five pounds. It was used in scenes where Humphrey Bogart carried it. Still, it's worth more than its weight in gold. The starting price is half a million dollars. The falcon was discovered by a movie producer at a flea market in New Jersey in 1991. He paid $8 for it.
