SYNOPSIS FOR NIGHT: =================== Never open. GENERAL COMMENTS (see Problems below for details): ================================================== It was snowing two hours before sunset, clouds at sunset, the humidity 82%. 18:00 everything inside the enclosure was ready to open but the wind took snow from trees into the air, so we couldn't open. 04:00 - the humidity is down to 75%, sky is clear, but we cannot open due to snowflakes flying in the air. 04:40 we issued the endNight and closed the business.
