The Pakistan Meteorological Department (PMD) has issued a weather forecast that promises a break from the scorching heat. Yet, it also raises concerns due to the intermittent rain and thunderstorms expected in the upper parts of the country from September 15 to 20.
Monsoon Currents from the Bay of Bengal
The weather advisory from PMD highlights that moderate monsoon currents from the Bay of Bengal are likely to penetrate the upper parts of Pakistan starting from the evening of September 15. This influx of moisture-laden air from the Bay of Bengal is the key driver of the anticipated weather changes.
Westerly Wave Arriving on September 16
Adding to the complexity of the weather situation, a westerly wave is expected to enter Pakistan on September 16. This convergence of weather systems sets the stage for a dynamic atmospheric interaction, leading to diverse weather phenomena.
Regions Affected by Rain and Thunderstorms
The impact of these weather patterns will be felt across a wide range of regions in Pakistan. From Kashmir in the north, including Neelum Valley, Muzaffarabad, and Gilgit Baltistan with its towns like Skardu and Hunza, to the central and western regions encompassing Islamabad, Rawalpindi, Peshawar, and Quetta in the south, the monsoon and westerly wave are expected to bring bouts of rain and thunderstorms.
Challenges and Precautions
While the prospect of rain is often a relief in a region where water scarcity can be a pressing issue, it also comes with its own set of challenges. The PMD’s advisory warns of moderate to heavy falls in several areas, which could lead to increased water flows in local nullahs (streams) and rivers. This could potentially pose a risk of flooding and necessitate precautionary measures by local authorities.
Landslide Concerns in Hilly Terrain
The mountainous regions of Pakistan, including Murree, Galliyat, Kashmir, Gilgit Baltistan, Chitral, and Swat, are at risk of landslides during this period. The prolonged rainfall can saturate the soil, making it prone to erosion and instability. Residents and travelers in these areas are advised to exercise caution and stay updated on weather alerts.
Relief from Hot and Humid Conditions
One positive aspect of this weather forecast is the expected relief from the prevailing hot and humid conditions. As the rain showers cool the atmosphere, residents can look forward to more comfortable weather.
The PMD’s weather forecast for September 15-20 presents a mixed bag of blessings and challenges for Pakistan. While the much-needed rain will bring respite from the heat and replenish water resources, it also necessitates vigilance, especially in areas prone to flooding and landslides.
