The weather looked threathening was looking gloomy in the morning. I guessed it was likely to rain soon judging based on the clouds. When I was about to go out for lunch, it rained suddenly. I had to come back to bring an umbrella.
It's getting pretty unpredictable, more and more like tropical weather, so I keep an umbrella in place at the company.
Most of the time, intermittent rain occurs these days. The Korea Meteorological Administration forecast often turns out wrong.

Hi Tony,

You made sure to make a composition even with a simple topic that you could write about. Few lapses were changed here so that it would be more fit to what you may want to convey. Overall, it was excellent.
