Climate change is real and has changed the temporal distribution of rainfall, often increasing the interval between rainfalls, while also increasing the amount that falls, during rainy periods.
Longer durations of 'no rain' cause the ground harden to a much less porous, concrete-like surface that cannot absorb the rain, when it does come, fast enough. So the water pools and flows, causing flood conditions.
