It is five seconds

5 seconds
I usually leave 5 to 6 seconds minimum following distance under those condition, and have had no accidents . . .
If it is raining and you are tired, you probably should not be driving - you are a hazard to yourself and other drivers when you drive in those conditions. However, if you must drive, keep a solid 10 to 15 seconds of following distance between you and the next car on the road.

Car lengths
4
three seconds plus following distance.
4 to 5 seconds
Usually in good conditions you want to have 2-3 seconds of distance between you and the car in front of you, for every hindrance (ie. rain) you add one second of distance. So in your case being both tired and having to deal with rain, i would say have at least 5+ seconds distance. I wouldn't recommend driving while sleepy as your reaction time and judgment decreases while tired, if you think you are getting too tired please pull over and take a quick nap.

Safe distance is 2 seconds, or 4 car lengths. More if snow is on the ground or its raining.
