Forecasters are expecting winds in Los Angeles to pick up late tonight and remain heavy over the next two days, a development that could reverse some of the hard-fought gains that firefighters made over the weekend. In anticipation, fire crews were deployed to at-risk areas.

The National Weather Service said the winds could lead to “explosive fire growth” and put in place a rare fire danger alert. The same warning was issued last week when intense winds stoked two of the deadliest fires in California history; the flames decimated entire neighborhoods and left evacuees with no communities to return to.

Here are the latest maps of the blazes. The largest, the Palisades fire, is now 14 percent contained; the most destructive, the Eaton fire, is 33 percent contained.

At least 24 people have been killed, and 23 others are considered missing. Here’s what we know about the victims, and the search for the missing.

Investigators have zeroed in on a ridge high above Los Angeles, where the Palisades fire is believed to have ignited, in their effort to figure out what caused the blaze. A recent visit by New York Times reporters to the site suggested a range of possibilities. This is what they found.
