The presidency has given further clarification on the bad weather which forced the cancellation of the visit to Zamfara State on Thursday by President Muhammadu Buhari in spite of the interest generated nationwide on the planned visit. Presidential spokesman, Garba Shehu, in a statement said as briefly explained by the president in a special broadcast to the people of the state, the sudden deterioration of the weather was the 'sole and only reason for the cancellation of the visit.'' According to him, ''It is not unusual for flights to get cancelled when there is bad weather, whether this is arising from wind or rainstorm, fog or haze as we had it on thursday over much of the northerns towns including Gusau, capital of Zamfara state. many of these cities are known to suffer from low visibility during the harmattan season as we are now in.'' Garba Shehu said, 'A kilometre of visibility is usually a standard landing minimum requirement but in the case of Gusau on the day in question, this minimum requirement but in the case of Gusau on the day in question, of 1,000 meter was down, flunctuating between 300-400 meters. Clearly, this was unsafe in the absence of precise instrument approaches that provide guidance for the pilots. The flights into Gusau were, in view of this, cancelled. ''criticism of the president, in particular the one by the opposition peoples Democratic Party, PDP, for not proceeding with the journey, Sokoto-Gusau by road, a distance of about 200 kilometres shows, either a lack of understanding of presidential movements especially for a party that held that office for sixteen years, or an act that smacks of mischief.''Â
