I have not set the trend setting in the alarm section. Does anyone have setting for like the pressure changing alarm?

High, low setting on like the temperature are more individualized but I figured the trend changes would be universal.

There really ought to be separate alarms for increase/decrease in pressure and temperature.

My thought is a rapidly falling pressure would tell me heads up for a storm. At least from my view point, a rising pressure would not be an alarm function but lots I do not know.

I just noticed the pressure units in the Alarm setting are in hPa/hr for the pressure change alarm even though all others are "in". I don't remember this coming up before or reading of an answer in the help file or wiki. If it is a small bug, I will make this part a post in the beta section if you like.

Yes, agreed. That's why they really should be separate alarms.

It's a bug in the units display for that item - it's really "in/hr" (i.e. that's what it expects); I'll fix the display, thanks.

Just as you thought here is an example of rapid rising pressure = bad things to come.

"A prime example(rising pressure) is in the snowbelt regions surrounding the Great Lakes when increasing pressure from an arctic high pressure system push strong, cold winds across the relatively warm lake waters to bury the lee shores in snow." Here they call it "Lake effect snow."

I am going to set my pressure alarm at
.06 in hg/hr = 2 mb/hr or 2 hPa/hr

Always interesting here at Cumulus.
