Weather tracker: US and Mexico brace for heatwave as deadly floods hit South Africa
"Heat is expected to intensify across western parts of the US and Mexico this week as a ridge of high pressure pushes temperatures well above the seasonal norm. Daytime highs are forecast to reach 10-15C above average in some areas. The US National Weather Service has issued heat advisories for parts of California and Arizona, with extreme heat warnings in force on Monday and Tuesday in places such as Palm Springs, where temperatures could reach 40-43C (104-110F)."
"More broadly, temperatures are expected to climb into the high 30s celsius before the heat shifts eastwards towards the midwest later this week. Meanwhile, severe weather is likely to continue across parts of South Africa, with disruptive rain and damaging winds raising the risk of flooding. Rain moved in from the Atlantic across the Western and Northern Cape on Sunday morning, bringing persistent downpours over much of the weekend."
"Between Monday and Wednesday, more than 200mm of rain could fall across parts of Western Cape, while mountainous regions could record totals approaching 300mm. The South African Weather Service has issued several warnings, highlighting the potential for flash flooding, mudslides, rockfalls and damage to infrastructure and property. Heavy rainfall is also expected to coincide with strong, potentially damaging winds."
"Large areas of southern South Africa, including Western and Eastern Cape, are forecast to experience north-westerly to westerly gusts exceeding 60mph (97km/h) early this week, with even stronger gusts likely over higher ground, particularly across the Cape Fold Mountains. The latest warnings come shortly after heavy rain triggered flooding, road closures and infrastructure damage across the Western and Eastern Cape on 5-7 May."
A ridge of high pressure is expected to push temperatures 10–15°C above seasonal norms across western parts of the US and Mexico. Heat advisories are in effect for parts of California and Arizona, with extreme heat warnings on Monday and Tuesday in areas such as Palm Springs, where temperatures may reach 40–43°C. High temperatures are forecast to rise into the high 30s Celsius before shifting eastward toward the Midwest later in the week. In South Africa, persistent downpours from the Atlantic have brought disruptive rain and damaging winds. Warnings indicate flash flooding, mudslides, rockfalls, and damage to infrastructure and property, with heavy rain totals exceeding 200mm and up to around 300mm in mountainous regions, alongside gusts over 60mph.
