We don't have the information for your vehicle but security system fuses should be hot at all trimes and is usually underhood. For other Civic models it is linked to the headlight relays.
Check the two fuses in diagram, underhood.
I don't see how rain has anything to do with it unless water is getting to the control unit and this could mean the unit is bad.
