The storm is said to be coming from Nigeria and is currently at the Ghana-Togo border.
A forecaster at the Agency, Patrick Lamptey, told Joy News on Monday the ?thunderstorm system?, which will be accompanied by high winds, will affect parts of the eastern coast, southern part of the Eastern region, and most parts of the Volta region.
The thunderstorm, according to Lamptey, is moving slowly, which means it will bring longer periods of rain in the affected areas.
?So where you have problems with drainage?and the landscape is not the best, you should expect flooding in those areas?, he warned.
According to the Ghana Metrological Agency, strong winds accompanying the thunderstorm could destroy billboards not well built.
He cautioned the public against moving along the streets in the areas where the storm is likely to strike.
He cautioned that because of the rainy season, the public must take warnings about the passing storm seriously and protect themselves.
In April, this year, severe rainstorm in Zabzugu in the Northern Region, injured four people and left over 300 others displaced.
