Severe Weather Awareness: Difference Between a Watch & Warning

The National Weather Service is the official issuer of a watch or a warning, based on expected weather conditions.

Stormcenter7 Meteorologist Brett Collar explains the difference.

In severe weather season, knowing the difference between a watch and a warning can be life-saving.

WATCH means you should prepare for the possibility of a severe storm or tornado.

WARNING means you should take action now, get to a safe location because severe weather is occurring or a tornado has been seen or indicated by radar.

Today: Flash flooding has been affecting the northern Miami Valley this afternoon, where 2 inches of rain has already fallen and this line of storms can drop another 1 to 2 inches as it slowly moves south and east. “I expect this to cross the entire Miami Valley from now through 6 p.m.,” Storm Center 7 Meteorologist Kirstie Zontini said. Isolated severe threat for damaging winds is the main issue..

Sunday: Temperatures will be in the middle 30s for most, but some may be a little colder. Light snow showers are possible with the flow off Lake Michigan. Road temperatures should help with any issues. A light coating on elevated surfaces can’t be ruled out. The day will be cloudy and still breezy with gusts around 25 mph. Highs will be in the upper 30s. Clouds decrease into the evening.

Here's a breakdown of what you need to know to get through the weekend:

Heavy rain: Today and this evening heavy rain and storms will move through. Minor flooding and ponding on the roads can be expected. 

Wind: Wind will be gusting this afternoon and evening. Winds more than 40 mph outside of any storms can be problematic. Isolated power outages are possible. Holiday decorations and lawn furniture could be blown around or damaged. Driving also will be difficult because of the strong winds, so leave space between you and the cars around you.
