Weather map illustrating atmospheric conditions across the U.S., including low and high-pressure systems, cold and warm fronts, and precipitation types such as rain, snow, and thunderstorms.

Let’s solve this step by step.

We are given a weather map of North America with symbols for fronts, pressure systems, and precipitation. We need to figure out what kind of weather is happening at location C.

Step 1: Look at where point C is on the map.
→ Point C is in eastern Canada, near Quebec (QC) and Newfoundland (NL).

Step 2: Check what symbol is right at or very near point C.
→ At point C, we see three horizontal lines: “≡”

Step 3: Use the legend (key) at the bottom of the map to find out what “≡” means.
→ Under “PRECIPITATION”, it says:
- ≡ = Fog

So, the weather at point C is fog.

Final Answer:
Fog
