If
you check the barometric pressure and find that [sic] it is reading
only 920 millibars ... two effects possibly responsible for this lower
than average reading are 1) elevation (~2500' MSL) or 2) a LOW
pressure weather system such as a mid-latitude or tropical cyclone. Also <span>A storm is approaching or barometer is read over a mountain</span>
