Pakistan Observer - - NATIONAL -

IS­LAM­ABAD —Mon­soon would likely to start in third week of June with 10-20 per­cent above nor­mal rain­fall forecast over the coun­try, with a spell of av­er­aged three months till Septem­ber.

An of­fi­cial of Met of­fice told APP that the El Ni¤o phe­nom­e­non has weak­ened and La Ni¤a is favoured to develop dur­ing the cur­rent sum­mer sea­son.

Pre­vail­ing oceanic and at­mo­spheric con­di­tions are giv­ing in­di­ca­tions of good sum­mer mon­soon rain­fall in the coun­try. Based on sta­tis­ti­cal and dy­nam­i­cal down­scal­ing of global cir­cu­la­tion models, out­look for the sea­son is pre­pared at 80 per­cent con­fi­dence level for plan­ning pur­poses. He said more than av­er­age rain­fall is ex­pected over Pun­jab, Khy­ber Pakhtunkhwa (KP), Sindh, Azad Jammu and Kash­mir and North­east Balochis­tan.

Some ex­treme rain­fall events are likely to oc­cur in the catch­ments ar­eas of ma­jor rivers and other parts of the coun­try, which may cause floods.

There is a high prob­a­bil­ity of heavy down­pour, which may gen­er­ate Flash Flooding along Sule­man Range, he in­formed. He in­formed that some heavy down­pour events may pro­duce ur­ban flooding in big cities, he in­formed adding, some strong in­cur­sions of mon­soon cur­rents, cou­pled with high tem­per­a­ture, may trig­ger Glacial Lake Out­burst Floods (GLOF), Land­slides and Flash Floods in Up­per KP and Gil­git Baltistan (GB). Mean­while, the Karachi Met Of­fice has forecast partly cloudy weather for Karachi dur­ing the next 24 hours. A Met Of­fice of­fi­cial said that max­i­mum tem­per­a­ture is ex­pected to re­main be­tween 33 and 35 de­gree centi­grade with 60 to 70 per cent hu­mid­ity in the metropo­lis dur­ing the pe­riod.

He said that hot or very hot and dry weather is likely to pre­vail over most parts of the province.

Partly cloudy with chances of driz­zle along the coast is also ex­pected. Dust rais­ing or strong gusty winds are likely to oc­cur at scat­tered places in Sindh over the next 24 hours.
