Not a warning. An alert comes after USGS publishes a quake, usually minutes after the shaking. For early warning use ShakeAlert, through your phone's Wireless Emergency Alerts or the MyShake app.
This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.
At this magnitude and depth, people at rest would likely notice it out to about 36 km (22 mi) from the epicentre. In Garnet, 15 km away, the estimate is intensity II (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.
Likely felt in: Palm Springs 10 km, intensity III · Desert Hot Springs 14 km, intensity II · Morongo Valley 18 km, intensity II · Idyllwild 19 km, intensity II · Cathedral City 20 km, intensity II · Banning 23 km, intensity II · Thousand Palms 24 km, intensity II · Valle Vista 29 km, intensity II. Estimated for each town centre; each link is that town's own record.
How big was it?
This earthquake released about 1,100 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.0 would have released about 32 times as much.

- Mineral, Virginia 2011 M 5.8 14,000× the energy of this one

- This earthquake M 3.0 about 1,100 lb of TNT
Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
For this area
The largest earthquake within 50 km since 2016 was M 4.5 on 2018-05-08 — about 150 times the energy of this one.
