| Notes | On the morning we were to do the route the forecast for the Boulder area on weather.gov was for a wind high of 34 mph with gusts to 53 mph by 2 PM. We decided to cancel and do the route another day. Later Liza looked up AccuWeather where the forecast was only 10 to 15 mph so we decided to go. By 2 PM the winds were up to an estimated 25 mph and an hour later was up to about 30 mph. This is not unusual in the Denver-Boulder area in winter caused by the Chinook winds https://tinyurl.com/435kwt7s | |
