PMD says a westerly wave may bring rain, thunderstorms, and isolated hail to multiple regions from 16–19 April 2026, raising risks of flash flooding, landslides, and travel disruption.
Key Takeaways
- A westerly wave is expected to enter northwestern Pakistan on 16 April 2026 and persist in upper parts until 19 April.
- KP, Gilgit-Baltistan, Kashmir, and parts of Punjab/Islamabad may see thunderstorms, gusty winds, and isolated hail, with snowfall over mountains.
- Balochistan may see rain and thunderstorms mainly on 17–18 April, while upper Sindh may face windstorms and dust-raising winds.
- Heavy downpours can trigger flash floods and landslides in vulnerable northern areas, especially around 17–19 April.
- Avoid unnecessary travel to hilly regions, secure loose items, and follow local advisories through the week.
What the Met Office is warning about and the key dates
Pakistan’s Met Office has forecast a spell of unsettled weather as a westerly wave approaches the northwestern parts of the country on 16 April 2026 and is likely to persist in upper regions until 19 April 2026. Under this system, rain-windstorms and thunderstorms are expected in several provinces, with isolated heavy falls and hailstorms in some locations. Snowfall is also possible over higher mountain areas.
The most active period is expected between 17–19 April, when storms can intensify quickly and bring gusty winds, lightning, and short bursts of heavy rain that overwhelm drainage. Even if there are occasional gaps, conditions can return suddenly, so planning should cover the full window.
Areas most at risk: upper KP, GB, Kashmir, and north Punjab
Khyber Pakhtunkhwa is expected to see rain-windstorms and thunderstorms with isolated heavy falls and hail from 16 April (evening) to 19 April, especially in upper and central districts such as Chitral, Dir, Swat, Kohistan, Mansehra, Abbottabad, Haripur, and Peshawar valley areas. Light rain and thunderstorms may also occur at isolated places in southern KP around 17–18 April.
Gilgit-Baltistan is also in the impact zone. Rain and thunderstorms with moderate to isolated heavy falls are expected in districts such as Diamir, Astore, Ghizer, Skardu, Hunza, Gilgit, Ghanche, and Shigar from 16–19 April, with snowfall possible over higher elevations. These conditions can affect road links in valleys where landslides and falling rocks are common after intense rain.
In Azad Jammu and Kashmir, rain-windstorms and thunderstorms with isolated hail are expected from 17–19 April, including Neelum Valley and Muzaffarabad region, with heavier falls more likely on 18–19 April. In Punjab and Islamabad/Rawalpindi, rain-windstorms and thunderstorms with isolated hail are expected from 16–18 April, including Murree and Galiyat, Islamabad/Rawalpindi, and major belt cities such as Lahore, Gujranwala, Sialkot, Faisalabad, and surrounding districts.
Balochistan and Sindh: thunderstorms vs dust and strong winds
Balochistan may see rain-windstorms and thunderstorms mainly on 17–18 April in areas such as Quetta, Ziarat, Chaman, Pishin, Qilla Abdullah, Qilla Saifullah, Zhob, and Barkhan. Localised downpours can reduce visibility and create short-term road hazards.
Sindh’s main risk in this forecast is windstorm and dust-raising winds in upper Sindh from 16–18 April. Dust events can trigger breathing discomfort, reduce visibility for drivers, and disrupt outdoor work, so simple precautions like masks and avoiding unnecessary travel during peak winds can help.
Safety advice for families, commuters, travelers, and farmers
Thunderstorms are risky not only because of rain, but because of wind gusts, lightning, and hail. Park vehicles under cover where possible, protect solar panels, and keep distance from weak trees and signboards during strong winds. Avoid sheltering under trees during lightning and stay away from power lines.
For travelers in hilly areas, the biggest threats are landslides and flash floods in streams and nullahs. Avoid unnecessary travel to Murree, Galiyat, upper KP, GB, and Kashmir routes during 17–19 April. If travel is unavoidable, check road updates, keep extra fuel and essentials, and avoid stopping near steep slopes that show fresh cracks or water seepage.
Farmers should be alert in hail-prone zones because hail can damage standing crops and fruit. If you have livestock, ensure shelter and dry feed availability. The key takeaway is vigilance across the full forecast window, because storms can pause and then return with little notice.
