FIFTH SPELL – COLA shows heavy downpour moving into Punjab

The fourth monsoon spell can weaken by July 22/July 23 in the north and in the coming week another monsoon (fifth monsoon) can aim towards the northern areas. PWP has observed some variation in the concentration of heavy rains in the fifth monsoon spell as COLA and GFS T574 shows the focus of heavy downpour in lower half of north Punjab that is Okara, Kasur, Sheikhpur, Faisalabad, Pak Pattan and few adjoining areas, COLA (not GFS) also shows light to moderate rains moving into south Punjab while on the other hand, US Charts shows (similar to past spells) concentration of heavy downpours over Islamabad, northern Punjab, Azad Kashmir and few parts of Khyber Pakhtunkhwa.

COLA and GFS (different version) show a low pressure moving towards Sindh during the last days of July and bringing heavy rains to much of Sindh including Karachi.

  1. Oh my! Loved this article! Terse yet accurate, good job! I really wish South Punjab, Sindh and eastern parts of Balochistan recieve some rain because just looking at the heat indices there makes me feel hot! Interestingly, rains reached Jhang and parts of central punjab but missed poor Faisalabad.

  2. The empty pocket in northern Pakistan in the Dust Cloud today, is exactly what helped cause the floods in 2010, where the monsoon moisture from India got stalled in the pocket. It will be interesting to see if the pocket persists, and if it stalls the monsoon again, because today’s Dust Cloud pocket looks identical to the pocket that formed on July 18, 2010, that you can see at http://www.ecoseeds.com/2010071818_g.GIF

  3. Nice article.It is raining daily here.As I live in the northern area of Islamabad we get frequent heavy showers.As Margalla Hills became a barrier for heavy,dark rain laden clouds stopping them going north.What will happen in Khaur and Islamabad.

  4. Babar Bhai Risalpur is getting heavy rain since two days. Are there chances of more rainfall in the fourth spell in Risalpur?

    1. As per PMD yesterday it was 71 mm and today early morning 101 mm was recorded. Yes there are chances of rain during the fourth spell as well.

    1. Yes there are chances of rain with thunder/lightning, at the moment, at the moment some weak thunderclouds are forming over KPK province.

  5. Dear Babar, AoA,

    Behtar tou yahi hai k aap apne portal ka naam ‘Pakistan’ k bajaye ‘Punjab & KPK’ portal rakh len coz sindh aur KHI k liye aap k pass koi good news nahi…agar hai sirf yahi ‘Dissipating cloud, dust cloud, weak low, cloud cover etc etc etc :( :( :( :( :( :(

    1. Walikum Assalam,
      When there is no major activity expected in those parts then what should I post about them! the pattern is active in KPK and North Punjab.

  6. As per -IOD, there would be less rains in the subcontinenet but what we havee seeing is totally opposit, India men theek thaak barshen ho rahi hen even pakistani punjab aur KPK men bhi hoi hen tou phir how we can say that theory of -IOD is accurate?

    1. I have mentioned to someone in the past as well just take the example of El-Nino the whole country got below normal rains while coastal areas got above normal rains. KPK and north Punjab are getting boost from western winds.

    1. 3 year myth that started from 1998 and continued in 2010, lets see if the myth is trusty as we still have September, October and November

    1. I think no proper rains expected during that time. GFS is more certain about last week of July, its just postponing the rains..

    1. Yes the GFS is showing widespread monsoon coverage over the sub-continent during the last days of July but it shouldnt be trusted right now :P
      I dont think so that heavy rains can roll in right now in Sindh around July 22.

      1. Well, At first GFS was showing the low pressure moving towards Utter Pradesh. Now it’s showing the low entering Sindh on 22nd :D

  7. @KM :

    I can’t understand what do these mean :

    precip_06 precip_12 precip_24 precip_48, Do these represt hours ?

    I share precip_48 model images with you.

  8. Finally a good news for Karachi, I hope it doesn’t change :)
    Insha’Allah we will see heavy rains from the last week of july and continue till 5th august :)

  9. @KM :

    Heavy lightning in the SE. It started 10 minutes ago and is still going on. Is it visible in your area ?

  10. Well well Guys, Tarim & Babar, thank you for leting us know some positive and good news….finally. I recently saw weather report on pTV where PMD Director Muhammad Hanif have said k 20th k baad but jald pore mulk me rain coverage increase ho gi aur sindh aur KHI men achi barish ho gi & i fully belive k that will happened.

      1. Why does it change SO MUCH ? :S
        I mean last night it was showing heavy rains in Sindh and now its showing no rains.

      2. Weather keeps changing and semi-desert areas have more unstable weather pattern than a tropical one.
        GFS changes once the weather changes, this is mother nature!!

      1. Then it will postpone it till mid aug then last week of aug then september then mid september then it will show no rains.

      1. In mumbai monsoon wind is directly proportional to sea breeze but in karachi sea breeze is inversely proportional to monsoon wind in summer.

      2. AOA babar bahi.Mai nai zadah tur logo sai yehi sunah hai kai mumbai mai barish sea breeze ki wajah sai hoti hai.Hatah kai yeh jawab sahi nahi hai.mumbai mai barish south western monsoon wind hi ki wajah sai hoti hai.bus difference yeh hai kai waha sea breeze west sai aahti hai tau monsoon wind bi south west sai hi aahti hai.Aur woh sea wind kai relative move kurti hai ais liyai mumbai mai baarshai bi zadah hoti hai .Aur karachi mai yeh condition reverse hai.yehi wajah hai kai south western monsoon wind waha zadah barish ka cause bunthi hai.Pur north eastern wind (postmonsoon season) mumbai mai barish ki aitni zadah wajah nahi buntah as compared to premonsoon season.kyun kai north eastern wind ki direction reverse hojathi hai sea breeze kai. jaisa kai karachi mai hotah hai.Baqi karachi aur mumbai ka temperature same hotah hai. waha bi sea breeze mumbai kai temperature ko maintained rukhti hai karachi ki tarah.pur monsoon season aahtai hi mumbai mai temperature aur humidity increase honah shurooh hojati hai.Aur sea condition bi rough hojati hai.Ais liyai waha kai fisherman bi may kai aakhur mai apni activities close kur daitai hai.

  11. The monsoon trough runs through Mumbai’s coastline that’s why they get heavy rains in the monsoon season.

  12. With this negative indian dipole, there will be no more rain, or, would monsoon weaken because of this??
    Is there a 5th spell expected in northern areas? 4th spell is by far the strongest.. :)

    1. Negative IOD causes cooler sea temperatures in the western Indian Ocean which causes less precipitation in the Subcontinent.

  13. Hmm thanks but I have to ask, since I dont even know the alif be of geography, what countries (or is it a part of a country??) are the subcontinent??

  14. SO, the entire subcontinent receives it’s rainfall from SW monsoon. -IOD weakens the SW monsoon which results in less precipitation in the Indian subcontinent.

  15. Tarim i also say the same thing which you repeat.Monsoon enter in the mumbai through coast line which is lie in the west direction.This condition is not coincide with karachi and also opposite of karachi.you also remember this tarim north eastern monsoon are not too much responsible for rain in mumbai.normally 72mm is average.The colour of the cloud is also black which is come from the west direction like karachi,But this is the monsoon cloud not the sea breeze cloud which people cannot understand.

  16. north eastern monsoon wind direction is opposite to the sea breeze in mumbai as similar to karachi.Therefore not too much rain is occur in mumbai .In the karachi stratus cloud which is the sea breeze cloud come from west direction and monsoon wind is come from north east.But my experience is that karachi get a rainfall similar to mumbai. if monsoon come from south west direction.In mumbai sea condition is also rough when monsoon come from south west. sea breeze help a monsoon to enter in the mumbai not resist monsoon like karachi.

    1. If the monsoon trough ran through Karachi’s coastline like Mumbai then we would we seeing monsoon clouds coming from SW direction like Mumbai.Monsoon clouds come from E/NE in Karachi via Bay of Bengal.

  17. Babar Bhai and Tarim bhai, i`m also very much interested in weather since my childhood but i dont have much knowledge to read graphs or maps which you people talk about like GFS & COLA. I daily search about weather on different sites many times a day. i Found your site 2years ago when i was randomly searching for monsoon and found your site :)

  18. plz pray for sindh rains .still no rain …day by day we specially people of sindh loosing hope of monsoon rains .A khuda humary gunah maaf farma aor hum pr apni rehmat barsaaa.

    1. Yes indeed, GFS shows some 80 mm rain from last days of July till first week of August.
      While COLA shows 100 to 125 mm rain from last days of July till first week of August.
      The rain stats will change tomorrow which is normal :P

    1. It is expected to remain till the end of monsoon season, it can be balanced in late August/September due to expected formation of La-Nina

      1. I cant say anything about it right now. Sub-continent hasnt seen an El-Nino in a while, the last chance erupted in 2012 but it didnt mature up.

  19. AOA. Babar bhai very little rain occured in Risalpur on 20 july. Is there Chances of heavy Rain in Risalpur?

    1. Yes, the sky is clear. It had been drizzling since July 13, it appears the moisture has run out, from coming week again the moisture will build-up leading to increase in SW clouds. Since the last 48 hours, the SW winds are weak while high level NE winds continue to be active.

    1. Yes, it was series of severe low pressures. In July 2011, UAC brought first rain to Sindh including Karachi :P remember that?

  20. PWP, in the 4th spell, we got one night of awesome rain on friday night. Last night, the clouds looked dark and very heavy as if ready to burst but there was no rain. Tonight, there are weak clouds, light in color, , is there chance of more rain or will we have to wait till 5th spell?? This 4th spell ended very early didn’t it??
    I am asking about Jalalia btw.
    Thanks.

    1. No chances of heavy rain in the North as the 4th spell has weakened significantly.
      Isolated rain/thundershower can occur.

  21. Sir a very good article.Is the coming week good for transplanting trees and other plants in Khaur Company please tell.When will very heavy rains hit Punjab.What will happen in Islamabad.

    1. Thank you Sardar, about plants you should ask a gardener.
      Fourth spell had the potential to drop very heavy rains as it did on its first day but due to the unexpected quick movement of WD 14 the intensity dropped significantly. There are chances of isolated heavy falls during fifth spell.

  22. Mark my words both Tarim & Babar, agar is moonsoon men KHI men proper rains na hoin tou phir Sep/Oct ya NOv men Cyclone formation confirm hai….you will see that soon.

    1. I’m sure no one wants that, neither do I or Babar bhai.
      We just want a wet monsoon season for Karachi and Sindh.

    2. i thk Cyclone Onil returns :) .. leken me sure ho july k ends se khi me ache barishe hogi leken spell weak hoga 2 or 3 days then early september me formation k chance hia cyclone k ;)

  23. Yes Tarim, i totally agree wid you k low will definitely move towards sindh as PMD forecasting it as well……. Lagta hai moonsoon PWD ko dodge de de ga aur PWD prediction sindh k bare men ZERO ki ZERO he rahe gi aur Babar agar aisa hua tou phir aap k uppar Penalty ho jaye gi aur wo bhi mazedar kisam ki :D

    1. PMD hasnt forecasted anything about Sindh yet, they believed that proper rains would occur on July 21/July 22 period in Sindh and that didnt happen, PWP in Monsoon of Pak said that isolated showers can occur during that period. Also its *PWP and please read the article completely, PWP has forecasted the possibility of rains during last days of July. PWP’s forecasted the pre-monsoon activity in Sindh it did occur, mid-week of July some showers were forecasted by PWP in Sindh, they occurred. In second week of July, a weak spell occurred in Sindh that was missed by PWP.

  24. Its not anyone’s fault Sindh and Baluchistan are dry areas.Look at these figures
    Karachi 6.6 inches
    Quetta 10.3 inches
    Hyderabad 6.8 inches
    Nawabshah 4.4 inches
    Sibi 5.6 inches
    Jacobabad 4.3 inches
    Dalbandin 3.1 inches
    On the other hand KPK ,North Punjab are wetter
    Murree 70.4 inches
    Islamabad 59 Inches
    Dir 57 inches
    Abbottabad 48 inches
    Peshawar 16 inches
    Lahore 19.3 inches
    Its not the Monsoon its the natural climate.

    1. 66mm average rain in the month of july and we still haven’t seen it last week of july is here now lets wait and see.

    2. The rains are below average and rain is always sporadic over Sindh and Balochistan. The averages don’t represent much because either it rains too much or it doesn’t at all.
      Islamabad on the other hand is not 59″ of rainfall. it is roughly 1200 mm at zero point which equates to 47.2″
