The Deputy Director of Ghana Meteorological Agency, Dr Ignatius Kweku Williams, has indicated that significant weather activity is expected across parts of Northern Ghana as thunderstorms and rain systems continue to develop. He explained that the most active weather conditions would be concentrated in the northern belt, particularly within the Upper East and Upper West regions.
Discussing the regional forecast, The Deputy Director stated that partly cloudy conditions are expected to persist alongside storm activity across several northern communities. Dr Williams noted that rainfall had already begun in portions of the Upper East Region and was gradually moving westward.
He identified Bolgatanga and Sandema among the areas expected to experience rainfall before the weather system extends into the Upper West Region. The weather expert added that the movement of the storm system suggests a continuation of showers into the late evening.
“Current weather patterns show active storm movement across the northern corridor. Areas within the Upper East and Upper West should prepare for rain and possible thunderstorms as the system progresses.”

Moving to Southern Ghana, where clouds cover is expected to remain dominant through the evening and into the next morning. The Deputy Director explained that coastal communities may experience light rain or drizzle during that period.
Additionally, Dr Williams indicated that isolated thunderstorms with rainfall may develop across parts of the transition belt. He stated that these occurrences are expected to remain localised and may affect only selected communities.
For Wednesday, The Deputy Director projected partly cloudy weather conditions across Northern Ghana. He added that sunshine is likely to become more visible during the afternoon, accompanied by intermittent cloud formation.
Moreover, Dr Williams stated that late afternoon conditions could trigger fresh thunderstorm development in the northern sector. He explained that such transitions are consistent with seasonal atmospheric instability across the region.
Discussing Southern Ghana again, he stated that cloudy weather will remain prevalent during afternoon hours. Occasional sunshine and brief sunny intervals are also expected across several southern communities.
The emphasis is on coastal areas, where slight rain or drizzle may occur in the morning. Later in the day, rainfall accompanied by thunderstorms is expected across sections of the middle and transition belts.
In light of the forecast, The Deputy Director urged the public to remain attentive to changing weather patterns. He indicated that conditions may shift quickly depending on atmospheric developments across the country.
Ground Saturation Raises Flood Risk Despite Lighter Rainfall
The Deputy Director explained that earlier rainfall projections for Accra that appeared less intense than initially anticipated. Dr Williams explained that atmospheric developments altered the expected outcome before the storm reached the capital.
He pointed out that moderate to heavy rainfall was recorded in areas such as Big Ada, Ada Foah and Breman Asikuma in the Central Region. These rainfall events, he said, confirmed that the broader forecast for Southern Ghana is still valid.
“Rain was recorded in several forecast zones as expected. The main storm system approaching Accra lost strength before reaching the city and much of its energy shifted seaward.”

Furthermore, Dr Williams explained that a developing storm system has initially shown potential to bring heavier rain into Accra. However, atmospheric energy weakened before impact, reducing the severity of the rainfall event.
He also highlighted the rainfall earlier in the week, especially the flooding experienced on Monday. The Deputy Director stated that the residual effects of those rains remain significant across several communities.
He said this gives rise to a major flood risk because the ground is heavily saturated. Even limited rainfall, he added, now carries greater consequences due to reduced absorption capacity.
“Although rainfall volumes may reduce, even small amounts can trigger flooding where the ground remains saturated. Previous floodwaters have already weakened the land’s capacity to absorb fresh rain.”

Moreover, Dr Williams urged residents in flood prone areas to be vigilant despite expectations of lighter rainfall. He advised the public to pay close attention to drainage conditions and official weather updates. The Deputy Director stressed that rainfall intensity may vary across localities, making timely alerts essential for public safety.
