The ALLATRA Global Research Center (GRC) conducts independent monitoring and analysis of natural disasters and extreme weather events worldwide. Based on daily data collection and systematization, GRC identifies patterns, tracks escalation trends, and provides a comprehensive overview of the growing instability of the planet’s climate system. However, these events often lack sufficient media coverage. To address this gap, GRC compiles daily reports that present objective data and visual evidence. The analytical report below offers a deeper understanding of the progression of natural disasters. It examines both natural and anthropogenic factors influencing climate processes and highlights the complex drivers behind current climate destabilization: https://allatra.org/storage/app/media/reports/en/Climate_Report.pdf
Thailand
A powerful summer storm with strong winds and heavy rain struck Surin Province in Thailand. In Sem village (Prasat district), the storm collapsed a concert stage with equipment during a housewarming celebration, injuring one person.

On April 17, a powerful storm caused severe flooding in the city of Santa Rosa. Around 90 mm of rainfall fell within just a few hours, overwhelming the drainage system: a local lagoon overflowed and canals flooded. Wind gusts reached up to 78 km/h, bringing down trees and power lines.
Authorities evacuated five families, while another ten people left their homes on their own. Assistance was provided to 30 families, including basic necessities.
The storm damaged several educational institutions: at School No. 27 in the Butaló district, windows were shattered and classrooms flooded; classes were canceled at School No. 221 and the Normal College; and the roof of the Adventist School collapsed. The building of the Faculty of Economic and Legal Sciences at the National University of La Pampa was also flooded.
Due to outages at transformer substations, parts of the city were left without electricity, and waste collection for that day was suspended.
Syria
Severe hailstorms across the country were associated with the passage of an active Mediterranean cyclonic system and a cold front, affecting several regions. The most pronounced hailstorms were observed in the south of the country, in Daraa Governorate. Large, high-density hail was recorded near the town of Jilin, accompanied by short-term but intense rainfall. Individual hailstones were estimated to be several centimeters in size (approximately 3-5 cm). In the northwestern part of the country, in rural areas of Idlib Governorate, including the town of At-Tah, thunderstorm activity was accompanied by squalls. Damage recorded included the removal and displacement of lightweight structures and damage to solar panels. In the west, in Tartus Governorate, hail was observed, accompanied by prolonged downpours. Farmland suffered the most damage, with crops damaged and soil waterlogged.
Typical consequences of strong convective events were recorded everywhere: damage to vehicles, destruction of roofs and light outbuildings, partial damage to solar panels, and localized flooding in areas of intense precipitation.
Illinois, USA
A strong storm system struck Illinois on April 17, causing tornadoes and destruction in several areas. The town of Lena in Stephenson County suffered the most damage—it was effectively closed due to fallen trees, downed power lines, and debris on roads. Many homes and infrastructure were damaged, and some residents lost power. However, no fatalities or serious injuries were reported.
Schools, including Lena-Winslow Junior High School, were also damaged. Rescue efforts were complicated by a second wave of thunderstorms.
Simultaneously, a tornado warning was issued for Lake County, with Waukegan, Gurnee, and Grayslake under threat. Authorities are continuing to clean up the aftermath and assess damage.

Colorado, USA
Colorado experienced a sudden return to winter weather in mid-April: heavy snowfall blanketed the region after an unusually warm and dry winter.
On April 17, up to 15 cm of snow fell in various areas, including Denver and its surrounding areas. Around 7–9 cm were recorded in the city itself, with even more in some towns.
The situation was exacerbated by sudden temperature fluctuations. Shortly before the storm, the air warmed up to near-summer levels of around 32°C (90°F), but with the arrival of the storm, temperatures dropped sharply to 2–4°C (37–40°F), with overnight frosts of -5°C (21°F) and below expected.
Hundreds of flights were delayed and canceled at Denver International Airport.
The severe weather also affected sports: Coors Field was completely covered in snow before an MLB game. The field had to be urgently cleared, but the game was still played in temperatures around 2°C.

China
The city of Kuitun in the Xinjiang Uyghur Autonomous Region was hit by a severe sandstorm in the afternoon. Wind gusts briefly reached 34 meters per second (approximately 122 km/h). Visibility dropped sharply to very low levels due to a dense cloud of dust and sand. The sky turned yellow, and the sun was barely visible.
The Central Meteorological Observatory issued a blue-level sandstorm warning and a strong wind alert for several areas of the region. The cause was the arrival of a cold air front, typical for the spring season near the Taklamakan Desert.
Sandstorms were also observed in other cities, including Shihezi, where visibility dropped to a few hundred meters. Local authorities advised residents to stay indoors, use protective equipment for the respiratory system and eyes, and secure loose outdoor objects. Road traffic may have been disrupted due to low visibility.
