Rajasthan to carry out India's first drone-based artificial rain trial today: Details of cloud seeding
The pilot project, aimed at inducing rainfall, will be inaugurated by state agriculture minister Kirodi Lal Meena at 2pm near Jaipur's Ramgarh Dam.
How will it work?
Around 60 drones will take part in the initiative, a joint effort between the Rajasthan agriculture department and GenX AI, a technology firm with bases in the US and Bengaluru.
The drones will spray special chemicals into clouds to trigger the formation of water droplets, which could lead to rain. The launch event will also be open for residents to watch.
The experiment, originally scheduled for July 31, was deferred due to heavy rain alerts. Since then, scientists have conducted multiple trials in Jaipur to ensure readiness.
The project has secured approvals from the Directorate General of Civil Aviation (DGCA), the India Meteorological Department, district authorities, and the agriculture department.
Last month, while speaking to ANI, Meena said, 'For the first time, artificial rain will be done via drone. For this, American scientists came here, and all the departments related to the environment discussed to decide this... The drones will take a very high altitude, and then this will be done via cloud seeding in Ramgarh Dam.'
What is cloud seeding?
Cloud seeding is essentially about giving clouds a gentle push to release rain or snow. According to Bloomberg, cloud seeding involves using chemicals, often particles of silver iodide, to trigger the formation of ice crystals or droplets from water that's already present in a cloud but not being efficiently turned into rain.
Though the technique has been studied for decades, it remains difficult to predict the additional rainfall that cloud seeding operations can generate, with estimates ranging widely from 0% to 20%.
Does it really work?
The science is promising, but not magic. Studies suggest cloud seeding can increase rainfall or snowfall by 5–15% under the right conditions. For instance, a major project in Idaho, USA, proved that silver iodide could indeed make super-cooled clouds produce more snow. But it doesn't work if there are no clouds to begin with.

Chicago flash flood warning and severe storms cause flooding, road closures, and flight delays
Synopsis Cook, DuPage, and Will counties, including Chicago, face flash flood warnings. Severe thunderstorms bring strong winds and heavy rain. Flights at O'Hare and Midway airports are temporarily stopped. Road closures occur due to flooding in Homewood. A new flood sensor network is launched in Chicago.

Heavy rain causes flooding and flight delays in Chicago as flash flood warnings remain active in Cook, DuPage, and Will counties. Photo credit X : @NWSFlashFlood A Flash Flood Warning is in effect for Cook, DuPage, and Will counties until 8 p.m. Tuesday. This also includes the City of Chicago. Flood Watch remains in effect until midnight Wednesday in Cook, DuPage, Will (IL) and Lake County (IN), as stated by ABC7 Chicago and FOX 32 thunderstorm warnings for Newton County until 6:15 p.m., Jasper County until 6:45 p.m., and Cook County until 4 p.m., including Evanston, Skokie, Oak Park — Winds could blow as fast as 60 miles per hour. Flood advisory for Central and north-central Cook County until 6:45 p.m., including the City of Chicago. Parts of Cook and Will counties until 5:30 p.m., with rain rates up to 3 inches/hour. Special Weather Statement for Will, SE Grundy, NW Kankakee, and SE Cook counties until 3:30 p.m. — strong storms moving at 25 mph with gusts up to 50 mph and half-inch hail. Storms moved into the Chicago metro area between 2 p.m. and 4 p.m. and are expected to continue over the same spots until 8 p.m, as per the report by ABC7 Chicago. ALSO READ: White House orders major Smithsonian review to remove divisive content and highlight American values Heavy rain from Monday plus Tuesday's storms could cause flooding issues — 1 to 2.5 inches of rain possible in Cook County at 1–2 inches per hour. Some storms produce 2 inches per hour of rain — flooding expected shortly after heavy rain starts, as reported by FOX 32. In Homewood, the Dixie Highway viaduct at the 17800-block is closed due to flooding. Homewood police helped a driver stuck in a car on Halsted Street; the car was towed and no one was hurt. Flights at Chicago's O'Hare and Midway airports were stopped several times on Tuesday because of storms. At first, both airports had stops until 3:15 p.m. Later, Midway's stop was extended until 4:15 p.m. and O'Hare's until 4:30 p.m. The final extensions kept flights stopped until 5:15 p.m. at Midway and 5:45 p.m. at O'Hare, as per the temperatures will go down to the upper 60s or around 70 degrees. On Wednesday and Thursday, it will be sunny with highs in the low 80s. Friday & Weekend: Heat returns — near 90°F on Friday, mid 90s on Saturday with heat index around 100°F, as mentioned in the report by FOX 32.

Artificial rain in Jaipur through pilot drone project to revive Ramgarh Lake
A pilot project to create artificial rain using drones was launched on Tuesday in Jaipur with the aim of reviving Ramgarh Lake and improving water availability in drought-hit areas of initiative, led by Agriculture Minister Dr Kirori Lal Meena, is the first in India to combine drone-based cloud seeding with artificial intelligence (AI).The technology, developed by US and Bengaluru-based firm Gen X AI, uses an AI-powered platform called "Hydro Trace" to identify suitable clouds for seeding using real-time data, satellite images and Once the right conditions are detected, drones release small amounts of seeding agents such as sodium chloride to help form 60-day mission will involve around 60 test flights, with drones expected to fly four to five times a month, depending on weather from the India Meteorological Department (IMD) will be processed to time the seeding project has approvals from the Directorate General of Civil Aviation, Agriculture Department, Meteorological Department and local the first day, the trial did not go as planned. The GPS signal was disrupted due to heavy mobile usage by the large crowd present, preventing the drone from reaching its target one attempt, it failed to lift off properly, and in another, it became stuck in bushes near the situation briefly caused tension between onlookers and police, but was brought under control. The technical team said future trials will have restricted public access and measures to avoid signal to Gen X AI founder Rakesh Agarwal, earlier cloud seeding efforts in India used aircraft over large areas, but drones allow precision targeting of small could make artificial rain possible in specific locations, such as farms affected by dry spells despite monsoon clouds. The team has been monitoring weather patterns in Jaipur for the past 20 Climate Engineer Dr N Sai Bhaskar Reddy of Excel-1, a partner in the project, said that Tuesday's plan was to fly the drone up to 400 feet, but current cloud formations are higher than that. The trial, originally scheduled for July 31, was postponed due to heavy rain Meena assured that the chemicals used are safe for people, animals and crops, and meet international standards. If successful, the project could help raise lake and groundwater levels, improve farm irrigation, and increase crop experiment is being funded by Gen X AI, which will share its findings with the Rajasthan government after two the trial works, similar operations could be launched in other drought-prone areas of the state and across scientist Kalyan Chakraborty said such drone-based precision cloud seeding has been used in the US before, but this is the first attempt in India.- Ends IN THIS STORY#Jaipur
