AST Blog: Sunday Night Storm Risk
A cluster of strong to severe storms is expected to develop across Texas and Oklahoma Sunday evening and push into southwestern Arkansas late Sunday night into early Monday morning. This is known as a Mesoscale Convective System (MCS), which basically is a large group of storms that can produce damaging winds, heavy rainfall, and localized flooding. While the storms should weaken as they move east, areas across central Arkansas could still see lightning and pockets of heavy rain early Monday. Copyright 2025 Nexstar Media, Inc.

Kerala: Heavy rains in Kannur, Kakkad river water-level rises; several areas waterlogged
Kochi: After heavy rains lashed Kannur (in Kerala) on Friday, the water level of the Kakkad river rose, leading to waterlogged areas in parts of the coastal city. Waterlogged roads slowed down traffic, and commuters faced significant difficulty. Many districts of the state received heavy rainfall, disrupting everyday life and causing waterlogging. The India Meteorological Department (IMD) issued red alerts for Idukki, Kannur, and Kasaragod districts and orange alerts for the remaining districts today. Authorities in several districts have declared holidays for educational institutions under their jurisdiction. As per the India Meteorological Department (IMD), strong westerly winds are likely to persist at lower tropospheric levels over Kerala and the Lakshadweep region for the next two to three days, resulting in widespread rainfall. The IMD stated, "Strong westerlies likely to continue at lower tropospheric levels over Kerala and the Lakshadweep region during the next 2-3 days. Under the influence of these, widespread rainfall activity with scattered Heavy rainfall to Very Heavy rainfall with isolated Extremely Heavy rainfall is very likely to occur over Kerala on 29th & 30th May 2025. Heavy rainfall is very likely to occur at isolated places over Kerala on 31st May, 1st and 2nd June 2025." District administrations across Kerala have declared a holiday for all educational institutions in several districts on May 30 (Friday). The precautionary measure applies to professional colleges, anganwadis, tuition centres, madrassas, and special coaching classes. With an Orange alert in effect for Ernakulam, a holiday has been declared for all educational institutions, including professional colleges. Anganwadis and tuition centers will also remain closed, as confirmed by District Collector NSK Umesh. All educational institutions, including Kendriya Vidyalayas, professional colleges, anganwadis, madrassas, and tuition centres, will remain closed in Kasaragod on Friday.

Weather tracker: China rainfall triggers flash floods and landslides
Southern China has been battered by heavy rainfall over the past week, triggering landslides and flash floods, especially in Guangdong and Guangxi. As of Saturday 24 May, at least four people had died and 17 were missing, adding to a toll of seven deaths from other recent events. More than 400 emergency personnel have been deployed to the region. Additional intense rainfall is forecast this week across south-western China, with more than 100mm expected in parts of Guizhou and Hunan on Tuesday, and totals possibly exceeding 80mm locally in Fuijan and 120mm in Zhejiang on Wednesday. Taiwan is also expected to have heavy rainfall this week as the weather system moves eastwards. New Zealand's South Island also faced torrential rain over the weekend, prompting weather warnings across the region. A front from the Tasman Sea brought heavy downpours and strong northerly and north-westerly winds, reaching gale force in exposed areas. Rainfall totals reached between 130-160mm in places on Sunday near the west coast, while significant totals were also recorded in Canterbury and Otago. The north-westerly winds brought moist air from the Tasman Sea, leading to heavy downpours after the air crossed the Southern Alps. The mountain range also heightened the winds, forcing air upwards to create turbulent and gusty conditions. Large parts of northern Africa, the Middle East, and southern Asia have experienced extreme heat in recent days. A dome of very hot air, stretching from Libya through Saudi Arabia and into Pakistan, pushed surface temperatures into the high 40s Celsius across a wide region last week, with some parts even exceeding 50C. In south-western Iran, a weather station near the city of Ashajari recorded 50.6C last Friday, while temperatures above 50C were also observed in parts of Pakistan, Kuwait, the UAE, and Saudi Arabia. While these regions are typically very hot at this time of year, temperatures of this magnitude are about 10-15C above the May average. In Iran, temperatures are approaching the country's all-time record of 53.7C, set in June 2017. Recent studies have found that the likelihood of such extreme heat in the Middle East has increased rapidly due to human-induced climate breakdown. According to a 2021 BBC analysis, the number of days during the 2010s with temperatures exceeding 50C had doubled compared with the 1980s, a trend expected to accelerate as global temperatures rise.

The floods and droughts in Australia are fingerprints of a warming planet
As New South Wales once again faces heavy rainfall and flooding, the Victorian towns of Euroa and Violet Town will enter stage 2 water restrictions next Wednesday. How is the climate crisis affecting these contrasting extremes? The weather pattern bringing heavy rainfall to NSW is a common wet-weather scenario for the coast. A high-pressure system in the Tasman Sea has stalled, and the anticlockwise air flow around the high is pushing moist air from the ocean over land. At the same time, about three kilometres above the surface, a low-pressure system is lifting the moist ocean air up. As moist air rises, it forms clouds, storms, and finally rain. While this weather pattern itself isn't unusual, the duration of the weather pattern is. Typically, high pressure in the Tasman may hang around for one to two days. But the current high has been there for the past four days, bringing unrelenting rainfall to NSW. The rain is falling on already sodden ground, increasing the likelihood of flooding. Sign up for Guardian Australia's breaking news email This is reminiscent of what we saw during the March 2021 floods. Unfortunately, the forecast for the next few days is also reminiscent of March 2021. After the rain from the east finally moves away, another strong band of rain is forecast to cross NSW from the west on Monday. Scientists are actively researching how climate change is shaping Australia's weather systems. We are not sure if weather systems will stall more often or not, mostly because we don't yet have the computing power to run high-definition climate models needed to study them. However, climate modelling capability is growing every year. Just last week, Australian climate scientists took part in a global hackathon to analyse data produced by models with about 50 times higher resolution than a typical one. Earlier studies using lower definition models suggest we may see a decrease in stalled high pressure in the Tasman Sea, and low-pressure systems may also occur less often but produce more intense rainfall when they do happen. While future high- and low-pressure systems are uncertain, atmospheric moisture is likely to increase in a warmer world. After the March 2021 floods, my colleagues and I assessed how often Sydney may experience persistently high amounts of atmospheric moisture over the region. High atmospheric moisture is a key ingredient in heavy rainfall, and when it sticks around for a while, persistent rainfall and flooding become more likely. We found that by 2080-2100, the chance of these high moisture events may increase by about 80% under both moderate and high emissions scenarios. With more moisture in the atmosphere, when low-pressure systems do occur and help convert the moisture into rain, the rain will probably be more intense due to global heating. As NSW sandbags, Adelaide is ramping up its desalination plant to ensure the city's water supply. Parts of South Australia, Victoria, Tasmania and Western Australia have received very much below the average rainfall over summer and autumn. Drought in Australia is largely driven by a lack of heavy rainfall events. Only one to five days of heavy rainfall per year can be the difference between whether there is a drought or not. The climate patterns in the Indian and Pacific Oceans, which influence year-to-year rainfall variability in Australia, have been in neutral or dry phases. Neither El Niño nor La Niña have appeared since autumn 2024. La Niña tried to rear its head over summer but didn't quite develop. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion The visually spectacular northwest cloudband, which can bring a band of rainfall from Broome to Hobart, has been absent this year. Instead, slow-moving high-pressure systems have brought frustratingly settled weather to southern Australia. Like flooding, the change in drought occurrence with a warming planet is still a leading topic of research in Australia. Since droughts are rare events, identifying trends in the data is much harder than identifying trends in maximum temperature, for example, which happens every day. The 'tinderbox drought' of 2017-2019 was the first drought in Australia where the severity would not have been possible without global heating. Additionally, southwest Australia has seen a robust rainfall decline since the 1970s, which is expected to continue. Droughts and floods have marked the Australian psyche for generations. But the fingerprints of a warming planet are starting to appear as increasing rainfall intensity and drought severity. It is undoubtedly clear that continuing to burn or export fossil fuels will increase the risk of extreme weather devastating Australia.

Heavy rainfall warning for Sunday in eastern Japan
Downpours hit parts of the Shikoku and Tokai regions from Saturday evening to early Sunday. Weather officials are urging caution against mudslides mainly on the Pacific coast side of eastern Japan. The Meteorological Agency says a low-pressure system accompanied by a front brought extremely heavy rainfall to Shikoku and Tokai on Saturday evening. Rain clouds developed over the Tokai and Kanto-Koshin regions through early Sunday. In one hour through 1 a.m., 71 millimeters of rain fell in Toba city in Mie Prefecture. In Shizuoka Prefecture, 31.5 millimeters of rain fell in Omaezaki City in the one-hour period through 3 a.m. Landslide warnings were in place for a brief period in Tokushima and Mie prefectures. Eastern Japan, particularly on the Pacific side, may get heavy rainfall in the morning hours as the front and low-pressure system pass over the region. Weather officials are calling on people to be on high alert for possible landslides, flooding in low-lying areas, swollen rivers, lightning strikes and gusty winds including tornadoes.
