A young japanese couple holding an umbrella walking down a street.
The young Asian couple are using an umbrella to protect themselves from the hard rain.
Just because the Asian couple is holding an umbrella doesn't necessarily mean it's to protect themselves from the hard rain, as Asian cultures also use umbrellas to shield themselves from sun as well.
We have no idea if there is hard rain out, it could be drizzling for sunny, people use an umbrella for a number of reasons.
You can not infer there is hard rain.
