An upper-level low-pressure center that used to be Tropical Storm Kay is swirling off the Southern California coast, spinning abundant tropical moisture into the Desert Southwest. Showers and thunderstorms will be developing Monday afternoon and evening, with heavy rains up to 1 to 2 inches in short bursts that could trigger areas of flash flooding.

"Kay is no longer, but the moisture from Kay is still sitting in the atmosphere, and that (moisture) is going to be funneled up back into the Southwest once again Monday as we have that southwesterly flow," said FOX Weather Meteorologist Jane Minar. "And it's going to work to reinvigorate the monsoon just a bit, so we do have the potential for flooding rains over the next 24 to 36 hours."
