TO Comments	Closed all night for radar, rain, dew point and clouds. Opened briefly to try to stack but got closed by Tracker dew point halfway through. Had some rain tonight. At EON, found a small puddle next to louver control box. Don't know how long it was there. We were pointed roughly into the wind at ~160 az for most of the night. Didn't find anything in the pier.
