Population over time
2 figuresPalo Verde fell from 171 to 152 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

| March 2020 | Flash Flood | Palo Verde | $60,000 | Scattered showers and thunderstorms, some with locally heavy rain, developed and moved slowly across far eastern portions of Imperial County during the afternoon hours on March 12th.

| July 2015 | Flash Flood | Palo Verde | $50,000 | Scattered thunderstorms continued to develop across portions of eastern Imperial county during the evening hours on July 19th. Due to an infusion of tropical moisture from former hurricane Dolores, some of the storms produced torrential rainfall which led to localized flash flooding.

There were no reports of accidents or injuries due to the flash flooding.

Some of the storms affected the community of Palo Verde, as well as motorists driving on highway 78. According to a trained weather spotter in Palo Verde, gusty microburst winds estimated to be nearly 65 mph caused trees to be snapped and downed at a local residence. The winds also generated thick blowing dust shortly before the heavy rains came. The strong winds also caused the power to go out. |

At 530 pm, radar estimated that over one inch of rain had fallen southwest of Palo Verde, and shortly afterward a Small Stream Flood Advisory was issued. At 615 pm, the California Highway Patrol reported flooding across State Route 78 approximately 3 miles southwest of Cibola.

| September 2012 | Thunderstorm Wind | Palo Verde | - | Thunderstorms developed across portions of eastern Imperial county during the afternoon hours on September 4th.

According to a trained weather spotter located in the town of Palo Verde, strong wind gusts estimated as high as 60 mph generated dense blowing dust at 5 pm. The visibility did not drop low enough to warrant a dust storm warning however. Fortunately, no damage occurred as a result of the strong wind gusts. |
