Plain English
What these alerts mean
A warning means the hazard is happening or about to; a watch means conditions favour it; an advisory is a lesser hazard still worth planning around.
A storm with hail of 1 inch or larger, winds of 58 mph or more, or both, is occurring or imminent. Move indoors and away from windows.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.
Extremely dangerous heat. Avoid strenuous activity, stay in cool spaces and never leave people or pets in a vehicle.
Sustained winds of 40 mph or more, or gusts of 58 mph or more, are expected. Secure loose objects and expect downed trees and power lines.
Critical fire weather: dry fuels, low humidity and gusty winds. Any fire can spread rapidly; avoid outdoor burning.

Questions
About Las Vegas alerts
How do I get Las Vegas weather alerts on my iPhone?
Install Forecast Bar, add Las Vegas as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Clark County then arrives as a push notification at the moment of issue, with Critical Alerts available for the most dangerous warnings. Forecast Bar also runs on iPad, Apple Watch, Mac and Apple TV.
Where do these alerts come from?
From the National Weather Service alert feed (api.weather.gov). NWS issues alerts by county and by forecast zone; this page lists every product that names Clark County, the county Las Vegas sits in. Forecast Bar checks the feed continuously and this page refreshes within a few minutes of a change.
What is the difference between a watch, a warning and an advisory?
A warning means the hazard is occurring, imminent or very likely: act now. A watch means conditions are favourable for it to develop: prepare and stay informed. An advisory covers a hazard that is less serious than a warning but can still cause real inconvenience or danger if you are not ready for it.
