ABS works basically by having a magnet "read" the speed of each individual wheel. It could be that one of the wires going to the magnet (sensor) is worn, and the rain water shorted it. Or, and I've had this happen, you got some road gunk stuck on the sensor, blocking it from reading.
Can rain cause my ABS light to come on?
Water common to both. Water in sensors, aquaplaning etc COULD cause ABS to get confused. Water in induction or sensors can cause limp mode. ABS and traction control lights both take signals from wheel rotation usually wheel too slow ABS and too fast traction control.
What causes the ABS light to come on and go off?
The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.

Can low tire pressure cause ABS light to come on?
The short answer is yes, low tire pressure can cause your ABS light to come on. The ABS (anti-lock-braking) system is responsible for maintaining contact with the road when braking. This suggests that you may have low tire pressure in one of your tires.
Can you drive with a broken ABS sensor?
Can you drive with a bad speed sensor? In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car's computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.
How long do ABS sensors last?
You can usually expect to get 30,000 to 50,000 miles out of your ABS speed sensor – more if you don't drive often, or if you live in an area where your car is seldom exposed to dirt, road salt, or other compounds that can cause damage to electronics.
