The Difference Between Warning and Watch and Other Weather Terms to Know
If you’ve ever gotten the bejeezus scared out of you when your phone goes nuts with an emergency weather alert that you didn’t understand, then this list is for you.
Let’s start with the basics:
Watches vs. Warnings
Watches are less intense than warnings. A watch means conditions are favorable for a weather incident to occur.
A warning means that weather incident is imminent or already occurring.
Examples of this are Thunderstorm Watch, Flash Flood Warning, Tornado Warning, etc.
What is a flash flood?
According to ready.gov, flash floods happen after excessive and heavy rain, or something like a dam break.
They ‘often have a dangerous wall of roaring water carrying rocks, mud and other debris. It can also occur when rainfall or snowmelt exceeds the capacity of underground pipes, or the capacity of streets and drains designed to carry flood water away from urban areas.’
Those massive road ponds that seem to spring up out of nowhere during heavy rain? Flash flood.
What is a thunderstorm?
A thunderstorm is any storm that produces lightning (which in turn, produces thunder.) They become classified as severe thunderstorms when they produce winds over 58 mph, a tornado, or hail with a one-inch or larger diameter.
A thunderstorm without rain IS possible, but unlikely in New Jersey.
What is the difference between a tropical storm and a hurricane?
The easiest answer is that all hurricanes are tropical storms before (and sometimes after) they become known as hurricanes.
A tropical storm is a cyclone storm that forms over the tropics, with sustained winds of 39-73 mph. When the sustained winds in that storm exceed 74 mph, it becomes a hurricane.
Hurricanes placed in categories from 1-5 based on wind speed: Category 1 is 74-95 mph, Category 2 is 96-110 mph, Category 3 is 111-129 mph, Category 4 is 130-156 mph, and Category 5 is 157+ mph.
Staying informed (and not panicking) is one of the best things we can all do when it comes to dangerous weather!
