ISLAMABAD, Sept 10: Though arriving late in the season but the rains have already caused considerable damages to southern parts of the country and the Met office has warned all the concerned authorities on Monday to remain alert during next 24 hours.

As the low pressure developing on Sunday has entered Sindh and adjoining areas, strong monsoon currents would continue to penetrate in central and southern parts of Pakistan, particularly in Sindh.

But the most serious point is that the ‘Westerly wave’ is also located over northern parts of Pakistan, but the system currently is too small and weak to pose a threat now.

The twin cities of Rawalpindi and Islamabad are also expected to receive mild to heavy showers on Tuesday, but heavy rains may cause more flash flooding in the vulnerable areas of D.G. Khan.

However, the good news is that the low pressure over Sindh, which has been enticing monsoon currents in southern parts of Pakistan, particularly in Sindh and Eastern Balochistan is likely to start weakening by Tuesday night.

The Met Office has said that widespread rain and thundershowers with isolated heavy falls is expected in Sindh during Tuesday, and the heavy rains may cause more urban and flash flooding in the vulnerable areas of the province during the period.

Similarly, in Balochistan, the widespread rains with isolated heavy falls is expected in eastern parts of Balochistan on Tuesday, which cause flash floods in Quetta, Zhob, Sibbi, Kalat and Nasirabad divisions. While isolated rain and thundershowers is expected in Khyber-Pakhtunkhwa, Kashmir and Gilgit-Baltistan.
