Drawing from official forecasts, this report aims to equip you with accurate, actionable information to navigate the day safely.
Current Weather Conditions in Ahmedabad
As of midday on September 28, 2025, Ahmedabad is experiencing partly cloudy skies interspersed with spells of light drizzle, setting the stage for more intense activity. The IMD’s latest bulletin reports light thunderstorms accompanied by lightning and surface winds of 30-40 kilometers per hour at isolated locations across the city. Humidity levels are high, around 80-85 percent, making the air feel oppressively muggy despite the moderate temperatures. Visibility is generally good at 4-5 kilometers but could drop rapidly with heavier rain.
Barometric pressure stands at approximately 1002 hectopascals, indicating a low-pressure system fueling the convective activity. Scattered cumulonimbus clouds, the harbingers of thunderstorms, have been observed over North Gujarat, including Ahmedabad, via satellite imagery. Early morning hours saw minimal precipitation, with only 2-3 millimeters recorded at the Sardar Vallabhbhai Patel International Airport’s weather station. However, by late morning, isolated thundershowers began dotting the radar, particularly in the eastern suburbs like Naroda and Vatva.
Urban heat islands in areas like Manekbaug and Satellite have amplified the discomfort, pushing the feels-like temperature closer to 38 degrees Celsius during brief sunny intervals. Water bodies such as the Sabarmati Riverfront are swelling slightly from upstream runoff, a precursor to potential urban flooding. Air quality, monitored by the Central Pollution Control Board, remains satisfactory with an AQI of 65, though dust stirred by winds could temporarily elevate particulate matter.
Residents in high-rises report flickering lights due to minor power fluctuations from gusts, while ground-level commuters navigate slick roads on Ellis Bridge and Ashram Road. Overall, the morning has been a deceptive calm before the storm, with the IMD predicting escalation by afternoon.
Understanding the Orange Alert
The IMD’s color-coded warning system is a critical tool for public safety, and the Orange Alert for Ahmedabad signifies “be prepared” for severe weather with high impact potential. Issued on September 27, 2025, and valid through October 1, this alert specifically highlights risks from heavy rain and thunderstorms. Unlike a Yellow Alert, which advises awareness, Orange demands proactive measures like securing outdoor items and avoiding unnecessary travel.
Scientifically, this alert stems from a trough of low pressure extending from the Arabian Sea to central India, interacting with a cyclonic circulation over the Bay of Bengal. This setup enhances moisture convergence, leading to intense convective cells capable of dumping 64.5 to 115.5 millimeters of rain in a single spell. Thunderstorms form when warm, humid air rises rapidly, cooling and condensing into towering clouds that unleash lightning and hail.
For Ahmedabad, the alert focuses on the period from 1:57 PM to 4:49 PM today, during which heavy rainfall is most likely. Accompanying hazards include squally winds up to 50 kilometers per hour, which could uproot trees or damage weak structures. The IMD classifies this as “very likely” at isolated places, meaning not city-wide but targeted bursts that can overwhelm drainage systems.
Historically, Orange Alerts in Gujarat have preceded significant events, such as the 2019 floods that submerged parts of the state. Today’s forecast aligns with active monsoon withdrawal patterns, where lingering systems deliver final heavy doses before tapering off. Understanding this alert empowers residents to mitigate risks, turning potential chaos into managed caution.
Detailed Forecast for September 28, 2025
Looking ahead through the day, Ahmedabad’s weather narrative unfolds in phases. From noon to 3 PM, expect increasing cloud cover with a 70 percent chance of moderate rain, totaling 10-20 millimeters. Thunder rumbles will echo across the city, with lightning flashes illuminating landmarks like the Adalaj Stepwell. Winds from the southwest at 20-30 kilometers per hour will carry the scent of petrichor, a welcome relief from the pre-monsoon haze.
By evening, as Garba sessions kick off around 7 PM, the probability of thundershowers rises to 80 percent, with heavier falls possible in central areas like CG Road and Navrangpura. Accumulated rainfall could reach 30-50 millimeters by midnight, straining the city’s aging stormwater drains. Temperatures will dip slightly to 28 degrees Celsius post-rain, offering a cooler backdrop for festivities.
Overnight, conditions stabilize with scattered showers and winds easing to 15-20 kilometers per hour. The moon, in its waxing gibbous phase, may peek through breaks in the clouds, adding a mystical touch to rain-slicked streets. For September 29, the alert persists with similar patterns: light to moderate rain at many places, transitioning to drier spells by October 1.
Satellite data from INSAT-3D confirms these projections, showing moisture plumes advancing from the Arabian Sea. Ensemble models from global centers like ECMWF and GFS converge on this wet scenario, with a slight uncertainty in exact rainfall quanta due to localized topography.
Impacts on Daily Life and Navratri Celebrations
Ahmedabad’s rhythm is inextricably linked to its festivals, and Navratri’s Garba is the heartbeat of September. On this 28th day, the Orange Alert poses unique challenges to these joyous gatherings. Venues like the Ahmedabad Municipal Corporation grounds and community halls in Paldi and Vastrapur are preparing contingency plans, including indoor alternatives or rain covers. Last year’s event saw crowds undeterred by drizzle, but today’s forecast of thunderstorms could scatter participants mid-dance, with lightning posing a real threat.
Traffic is another casualty. Major arteries like the SG Highway and Narol Road are prone to waterlogging, delaying commutes by 30-45 minutes. The Ahmedabad Traffic Police has issued advisories to avoid flooded underpasses, such as those near Prahlad Nagar. Public transport, including AMTS buses, may face delays, while auto-rickshaws haggle over wet routes.
Economically, street vendors selling Garba attire and snacks brace for reduced footfall, potentially losing thousands in daily revenue. Farmers in surrounding Kheda and Gandhinagar districts worry about crop damage; standing cotton and groundnut fields could suffer from waterlogging, impacting the Kharif harvest.
Schools and colleges, already in festive mode, might shift to online classes if rains intensify, affecting over 500,000 students. Healthcare facilities like Civil Hospital are stocking up on electrolytes for heat-rain related illnesses like diarrhea. Positively, the rain could replenish groundwater, benefiting the parched Sabarmati basin long-term.
In essence, while the alert disrupts, it also fosters community resilience, with neighbors sharing umbrellas and stories under one roof.
Safety Precautions During the Thunderstorm
Navigating a thunderstorm requires more than an umbrella; it demands smart strategies. First, stay indoors during peak alert hours, avoiding open fields or metal structures that attract lightning. The “30-30 rule” applies: if thunder follows lightning by less than 30 seconds, seek shelter immediately, and wait 30 minutes after the last rumble.
For drivers, slow down on wet roads to prevent hydroplaning, and use headlights even in daylight. Pedestrians should sidestep puddles to avoid electrical hazards from frayed wires. In Garba venues, organizers must ensure lightning-safe zones, with evacuation drills in place.
Home safety includes unplugging appliances to guard against surges and securing loose objects like satellite dishes. For the vulnerable—elderly and children—keep emergency kits with torches, first-aid, and dry clothes handy. Hydration remains key despite rain, as humidity saps energy.
Authorities recommend downloading the IMD app for real-time updates and tuning into Akashvani for bulletins. In case of flooding, move to higher ground and contact the disaster helpline at 1077. By prioritizing these steps, Ahmedabadites can weather the storm unscathed.
Historical Weather Patterns in Ahmedabad
Ahmedabad’s climate is a tapestry of extremes, shaped by its semi-arid location at 23 degrees North latitude. September marks the monsoon crescendo, with average rainfall exceeding 150 millimeters. Past years offer lessons: the 2017 deluge brought 200 millimeters in 24 hours, paralyzing the city and claiming lives.
Thunderstorm alerts have surged 20 percent in the last decade, linked to climate variability. The 1920s saw milder monsoons, but post-2000, erratic patterns emerged, with 2023 recording the wettest September on record at 250 millimeters.
These events influence urban planning; post-2005 floods, the city invested in BRTS corridors with elevated designs. Historically, Ahmedabad’s weather has mirrored societal shifts—from Mughal-era aqueducts to modern smart city initiatives.
The Role of IMD in Weather Forecasting
The IMD, established in 1875, is India’s sentinel against nature’s fury. Its Ahmedabad office, operational since 1920, employs Doppler radars and automatic weather stations for precision. The Orange Alert exemplifies their prowess, integrating numerical models with ground observations.
Recent advancements, like AI-driven nowcasting, enhance accuracy to 85 percent for short-term forecasts. During alerts, IMD coordinates with state disaster management, disseminating info via SMS and social media.
Their bulletins, like the one issued today, detail impacts and actions, empowering proactive responses. As climate challenges mount, IMD’s evolution—from barometers to satellites—ensures Ahmedabad stays ahead of the clouds.
Broader Implications: Climate Change and Urban Resilience
This Orange Alert is a microcosm of larger shifts. Gujarat’s monsoons have intensified by 10 percent since 1950, per IPCC reports, driven by warmer oceans fueling stronger cyclones. Ahmedabad, with its 8 million residents, faces amplified flood risks as concretization reduces permeability.
Climate adaptation includes green roofs on new builds and wetland restoration along the Sabarmati. Navratri’s carbon footprint—from generators to travel—adds to emissions, prompting eco-Garba initiatives.
Globally, similar alerts in Mumbai and Chennai highlight South Asia’s vulnerability. Mitigation demands policy, like the Gujarat Climate Change Action Plan, targeting 15 percent emission cuts by 2030.
Yet, hope lies in innovation: rainwater harvesting in 70 percent of households could offset deficits. This storm, then, is not just rain—it’s a call to build resilient futures.
Conclusion
As September 28, 2025, draws to a close in Ahmedabad, the Thunderstorm Orange Alert encapsulates nature’s dual face: destructive yet life-giving. From morning mists to evening echoes of thunder, the day tests the city’s mettle. With light to moderate rains nourishing the earth and winds whispering change, residents emerge stronger, their Garba steps perhaps a tad more cautious but no less spirited.
Heeding IMD’s wisdom, embracing safety, and reflecting on history, Ahmedabad dances on. Tomorrow promises clearer skies, but today’s lesson lingers: in the heart of monsoon magic, preparation is the truest celebration. Stay safe, stay informed, and let the rains renew.
