Thanks guys, I'm pretty sure that's where I picked up the water.

Not aware of any alarm based on air filter restriction, but sure would not drive with a water soaked air filter-- very likely to break up under vacuum of running the engine and at the very least allow dirt into the engine-- water into engine (hydrolock if enough water) even worse.  Wet paper is not very strong!

Any number of things could set off the alarm in wet conditions-- a few are antenna up alarm (usually a short on the roof), engine temperature or oil pressure sender shorting due to water, jack alarm, etc.  If you have a schematic of the alarm wiring, pull out your digital VOM and start with those circuits.

 I am ready to address the sensor/rain issue. I plan on using a spray electronic cleaner, then blowdrying w/compressed air and packing the connections with dielectric grease. can I use too much grease? and is this the route to go? I plan on doing this to every connection I can find.
 I appreciate everyone's help.

Mitch,

I would just replace the roof mounted "antenna up" switch-- they are only a couple of bucks and if it has gotten water in it, it is not worth trying to repair.  Just remove and take to any store that sells parts for home alarm systems.  They can tell by looking if it is a normal open or normal closed switch.

And for the "under coach" connections such as oil pressure and water temperature, your approach is correct: clean, sand metal with 1000 grit if you don't have a clean metal surface (or replace the connector). Then apply dielectric grease and get a good tight connection.  You don't need to get messy with huge amounts of grease, but coat all the metal.  Basically, you are isolating the sender(s) so that muddy water will not provide a partial ground path and trigger an alarm.
