LasVegas weather radar offline after lightning strike. Some coverage from other radars but will leave some gaps(these feed your apps too). Airport radar TLAS only provides short range.

These ‘little things’ here/there add up over time in large scale weather events. 19Aug #Hilary

Road not closed so its okay?
"Turn around don't drown!"
In large scale flood events authorities don't have the resources to monitor and close every single road that's flooded! Use common sense. If flooded just turn around. And don't drive around barricades in place.

"Turn Around, Don't Drown"
Did you know?
The majority of flood related deaths in the US are people in their cars??
If you can't see the road then you don't know it's still there, how deep, how fast, etc. And your cars computers are typically mounted low = easy to stall/fry them $

What are Key Messages?
There's a lot of storm information text, graphics and data. Key Messages graphics provide a brief summary of important information about a specific tropical system. This may include safety and storm hazard information, future track guidance, confidence, etc

Wait...why is Warning bad in weather but good when shiny blue lights are behind you while driving??

Yes, it's the opposite...

In Weather 'Watch' means ingredients in place to happen, but 'Warning' means it is occurring or imminent and to take action.

Wind speed probability maps can help show percent chance of seeing 39mph or higher winds due to a tropical system. Keep in mind this is just winds from a tropical system...it won't show winds from other sources that may occur here. Check with local NWS for additional information.

The arrival time of winds map can help tell you when winds of 39mph or higher starting time may occur due to a tropical system. For the US East coast, that's enough wind speed to start to cause downed trees, scattered power outages.

Why is top 'S' dot white for Monday while others darker?
The dark S (Tropical Storm), dark H (Hurricane), dark M (Major Hurricane (Cat3+)) are tropical system intensities.

White dot means not expected to be 'tropical' anymore, just a regular old Low. Impacts same/similar though.
