A welcome rainstorm in mid-October provided the first significant relief from months of very hot and dry weather — and then the weather turned hot and dry once again. That cycle is a reminder of two important facts of life of San Diego County:

• On average, we get about 10 inches of rain a year — far less than what we need to sustain our $220 billion economy and 3.3 million people.
• With continued investments in water supply reliability and water-use efficiency, we can continue to thrive in this amazing place.

As we look toward the rainy season, it’s worth taking stock of why we have sufficient supplies for 2019 regardless of the weather.
