Most San Diegans woke up Monday to puddles or downpours, a welcome respite from the 40-plus day drought the region had experienced. The county's first significant rainstorm of the season brought totals Monday ranging from a quarter to half an inch near the coast to more than an inch in the mountain slopes, according to the National Weather Service.

Scattered rain showers fell across San Diego County over the weekend, bringing some slight respite during what the National Weather Service has referred to as the driest start to San Diego's water year.

The National Weather Service says there is a chance of thunderstorms into Monday, while there is a chance that rain may hang around San Diego until Wednesday. Maximum rain rates could exceed 0.3 inches per hour Sunday,
