Patiala, May 21 -- Punjab and Haryana are reeling under a severe and persistent heatwave, with the India Meteorological Department issuing an orange alert for most parts of both states. Officials have warned that hot and dry conditions are likely to continue without significant relief until at least May 26, as temperatures remain well above seasonal norms across the region. Rohtak and Bathinda were the hottest in the region, breaching the 46 degrees Celsius mark on Wednesday. In many places across Punjab and Haryana, maximum temperatures hovered close to 45 degrees Celsius. Other major cities in Punjab also remained under severe heat stress, with Patiala touching 45degC, Chandigarh 44.4degC, Ludhiana 44.1degC, and Amritsar 43.6degC. Overall, the average maximum temperature in Punjab has increased by around 0.7degC in the past 24 hours and is currently about 4.6degC above normal, indicating sustained heatwave conditions. In Haryana, Sirsa sizzled at 46.2degC, Narnaul 45.6degC, Bhiwani 44.5degC, Gurugram 44degC, while Karnal's maximum settled at 43.7degC. Amid a severe heatwave, the Haryana government on Wednesday declared summer vacation for all schools from May 25 to June 30. According to the IMD's Chandigarh meteorological centre, weather conditions across Punjab and Haryana have remained predominantly dry over the past 24 hours, with only isolated instances of gusty winds reported in some areas. The forecast indicates that this dry spell is likely to continue across the two states until at least May 26. While a brief and minor moderation in temperatures may occur in isolated pockets during May 22-23, it is unlikely to provide meaningful relief from the ongoing heatwave. Weather models suggest that southern and central Punjab districts - including Bathinda, Mansa, Muktsar, and adjoining areas - will remain under the most intense heat stress. These regions are expected to continue experiencing severe heatwave conditions over the coming days, with prolonged exposure increasing the risk of heat-related illnesses. The orange alert issued by the IMD signifies "be prepared" conditions, warning of possible health impacts and disruption to normal life. Medical experts caution that prolonged exposure to extreme temperatures can lead to dehydration, heat exhaustion, and potentially life-threatening heat stroke, if not treated promptly. Vulnerable groups such as children, the elderly, outdoor workers, and individuals with pre-existing conditions like hypertension, diabetes, heart disease, and respiratory illnesses remain at higher risk. Authorities have urged residents to avoid outdoor activity during peak afternoon hours, typically between 12pm and 4pm, and to maintain adequate hydration throughout the day. People are advised to wear light, loose cotton clothing, use protective coverings such as caps or umbrellas when outdoors, and keep living spaces as cool as possible....
