I like to get daily forecasts from a local area TV Station. Being aware that most weathermen/ women hilight the negative aspects of the forecast.
Usually the first notice of bad weather in my immediate area is the satellite TV quits working.
Most very important thing is to know where you are and have a paper map so you can see where the real bad weather is and track where they are predicting it will go.
I like Intellicasts web site, and use it. Doesn't really matter which app you use. Most like Accu-Weather, Intellicast, Weatherunderground are all owned by Weather.com/ Weather Channel and show the same information.
None of the online services make predictions. That comes from the NWS and only the NWS issues alerts.
I've been in one tornado situation while in my RV. That was Dallas/ Garland on Dec 26, 2015. I used to live in that area, and I watched WFAA TV live on my phone.
Nothing beats a local TV Station for street by street / block by block tracking of a tornado. It also helped greatly that I knew the area and could follow the tornado without having to look at a map. It passed less than a mile east of us. Was night so didn't see it for certain, might have caught a glimpse.
Do not trust your RV to protect you in a tornado. Get inside a solid walled shelter or building.
