More passenger trains are being added between two Southern California cities this year. The Biden Administration has awarded a $27 million federal grant to the LOSSAN Rail Corridor Agency to add additional Amtrak Pacific Surfliner service between Los Angeles and San Diego.

The smoke has yet to settle in Southern California, where thousands are reeling from the devastating impacts of a series of ongoing fires in the Los Angeles area. Just how far are they from San Diego?

Forecasters say the winds in L.A. have followed a favorable path to the sea. That path shifts to San Diego on Thursday night.

Smoke is drifting to cities miles away from where multiple major wildfires are burning in Los Angeles County, prompting several air quality alerts, but will it reach San Diego County? No air quality alerts have been issued in San Diego County as of Monday but NBC 7's team of meteorologists is tracking wind movements to determine whether locals will begin to see or smell smoke.
