An Opel Corsa wades slowly through the storm water that flooded Valley Road, in Birkirkara, yesterday afternoon as a heavy thunderstorm hit the islands. The bad weather, which lasted about an hour, caused long traffic queues. An electricity pole in Xagħra was damaged when it was hit by lightning. The police also cautioned drivers to avoid the Saqqajja hill in Rabat as part of the road had collapsed. The weather today is expected to be partly to rather cloudy with the possibility of thundery showers at times.
