We had a storm warning with wind and rain warnings on the BC coast. I don't have my weather station yet, but I was monitoring the BP readings from the airport using an app and saw the BP rising, and rising, and rising. Everything I've read and understood suggests that I should have been expecting a drop, but a big drop never came. The big storm hasn't come yet either. Yes, the BP is falling again, about the same rate that it rose. I guess it could still drop rapidly, but I was beginning to doubt my knowledge, especially given that it's very basic.
So, what conditions can cause the BP to rise (101.5 to 102.5 in about 12 hours) while a storm is barrelling down beside us?
