LINVILLE â The State Climate Office of North Carolina recorded a 97.7 mph wind gust on Friday, March 10, at Grandfather Mountain, officials confirmed. The State Climate Office noted the 99.7 mph wind recorded in the 10 a.m. hour was the highest recorded so far in 2017, surpassing the Jan. 18 high of 89.5 mph.
Compared to 7.5 mph, at 15 mph, the wind force against a tent is 4 times as great. Campers should note that as the wind speed (mph) doubles, the wind force (psi) against a tent wall quadruples. The wind force at 15 mph is significant, but manageable with most family tents. This wind speed threshold approaches the manufacturer's wind rating for many family tents, which is about 17 mph.
