That's the airbag monitor system telling you there's a diagnostic fault code for the airbag. It's usually a 2 digit code that describes the error it detected. I don't know what the codes are for a '98.5 but it indicates that something in the system may be getting flaky. Watch the lamp when you turn the key on and see if it flashes any codes, other than turning on continuously for several seconds during "prove out".
On a '95, it can be any one of a dozen and a half codes from 12 thru 53. You may have had some wiring getting weird at the front crash sensors because of the heavy rain. Rapid continuous flashing (no codes) means that all primary crash sensors are disconnected. A series of 5 "beeps" (sound, NOT lamp flashes) repeated 5 times, every 30 minutes while the ignition is ON indicates the airbag lamp is burnt out.
If you don't know what you're doing, airbags shouldn't be messed with since you can accidentally set them off.
