Look for plastic bungs in the floor pan, ideally one each side of the transmission tunnel. Pop the bung(s) out to give the water somewhere lower to drain to. Use something like a clean paint roller to squeegee the water in the direction of the bung hole. The amount of spray likely to enter the car via the bung hole is minimal. Leave some newspaper in the car to help soak up the water. Change it frequently.
If you are sure that the original cause was the blocked hood drains (Check the door cill drain holes are clear as well) and the car is now watertight with the hood up, then remove the hard top and drive with the hood down and heater on as long as the weather is suitable. The MX5 heater is quite powerful and will cope with low temperature. Ventilation is an enormous help with drying things and hood down is good ventilation.
Replace bungs when necessary.
