Karachi is currently witnessing a rare phenomenon: a sun halo, which is a signal of heavy rain.
According to meteorologists, a sun halo, which occurs when the sun is surrounded by specific types of clouds, is a clear indicator that heavy rain will occur within 24 hours.
There are many old farmers’ sayings that are used to predict the weather. One such saying is, “If the sun has a halo, rain to follow.
When you see a halo around the sun, that is an indicator that there is moisture high in the atmosphere. If the halo is followed by high, thin, wispy cirrus clouds, then there is a storm system approaching you. It’s typically 24 to 48 hours away.
It isn’t a guarantee that precipitation is coming since the storm may miss you. For example, if the cirrus deck is in our southern sky and the clouds are moving east, the storm will likely miss you to the south. However, if that cirrus deck is to your west, more than likely you will see precipitation in a day or two as most of our weather comes from the west.
