Weekend weather update: Millions set for weekend drenching
Millions of Aussies are set for a weekend soaking with extensive rain and wild wind forecasted as a deep cold front pushes across the nation. The Bureau of Meteorology Meteorologist Mirium Bradbury said on Thursday afternoon a 'broad reaching rain band' was moving across the country, with 'damaging winds likely for some parts of Australia over the coming days'. 'Fairly widespread moderate rainfall totals across much of Australia over the coming days as this rain system moves eastwards,' she said. 'But the area I really want to focus on is this area in the southeast, including parts of South Australia, western Victoria and inland NSW. 'These areas have seen significant rainfall deficits over the past six, 12, even 18 months. 'The rain that we're expecting over the coming days is not going to do too much to dent these long term deficits, but it is going to be good news for many of our communities through these very dry parts of Australia. However, it's not without its own hazards.' Ms Bradbury warned 20 to 40mm was expected for many areas through South Australia and western Victoria with roads at risk of flooding. 'This could lead to very dangerous driving conditions, as those roads grow slippery with the rain and visibility reduces as well. 'The other key impact we're expecting as this system moves across the country are the damaging winds. 'We've already issued severe weather warnings for damaging winds across four separate states of Australia. Queensland, the Northern Territory, South Australia and Western Australia. Ms Bradbury said that the risk of damaging winds was mainly focused on Friday but the south coast of Western Australia could see some damaging gusts through Thursday evening. 'So what's driving all of this wet and windy weather? The answer to that is a cold front,' she said. 'It crossed the west coast yesterday, bringing some fairly significant thunderstorms to the Perth area and it's now moving across those inland parts of Western Australia, directing a broad rain band across much of WA. 'The system is attached to a low pressure system sitting to the south of the continent, and that low is going to help push this cold front and the rain band eastwards over the next few days.' Heading into Friday the cold front is predicted to pull the rain band eastwards and introduce rain across eastern parts of South Australia, Western Victoria, NSW and southern parts of Queensland. 'The rain will be widespread, soaking and lasting for a number of hours. Unlike the patchier showers we're expecting to pull up behind that frontal system. 'The winds are also expected to really increase through the course of (Friday). 'That band of strong winds shifts into the eastern states late Friday into Saturday as the front pushes eastwards and we see those strong winds moving across the east coast through the course of Saturday, before the system gradually starts to move offshore and the winds start to ease.' Ms Bradbury advised keeping on top of all warnings and updates especially for the areas most in the firing line around eastern South Australia, Victoria and inland NSW. 'Friday and Saturday are definitely looking likely to be the wettest days as this system moves across the country.' Outside of the cold front Darwin remains clear with light winds highs of 31 and lows of 22 over the weekend. Brisbane will see some lingering showers after the weekend before dipping on Tuesday to a minimum of 9 degrees. Melbourne and Sydney will likewise experience scattered showers with temperatures expected to be within the normal range for this time of year. After the weekend soaking Adelaide is expected to remain cloudy with north-easterly winds of around 20km/h.

Millions under threat of extreme heat. Do you live in the 'danger' zone? See heat map
While Texas bakes under sweltering conditions, it's far from alone. Millions are under threat of extreme heat this week, as experts warn that temperatures will reach triple digits almost daily for the next few weeks. Extreme heat warnings, advisories and watches are in effect across several states Wednesday, July 23, as a powerful heat dome tightens its grip over the Mississippi Valley. The National Weather Service says the dome will slowly expand eastward through the week, pushing dangerous temperatures and stifling humidity into new regions. In many areas along and east of the Mississippi River, heat index values could soar to between 110 and 115 degrees — the kind of oppressive heat that can quickly turn dangerous without proper precautions. By Thursday, July 24, the dome's reach is expected to stretch into the Great Lakes and Northeast, bringing the intense summer scorch with it. "While this is not really a record-breaking air mass in terms of high temperatures, some towns and cities will struggle to drop below 80 degrees at night due to the high humidity levels and retention of heat by vast areas of concrete and pavement," AccuWeather Senior Meteorologist Brett Anderson said Wednesday. "For those that only have a fan or open window to keep cool, sleeping will be difficult for some, with a high risk of dehydration." And in Texas, summer doesn't just hit harder — it sticks around longer. The first 90-degree days are arriving earlier, and stretches of triple-digit heat are lasting longer than ever, a USA TODAY analysis found. National heat index map: How hot is it in your city? The map below identifies areas where the heat index is forecasted to reach NWS-defined levels from "Caution" (80 degrees Fahrenheit) to "Extreme Danger" (above 125 degrees). The heat index measures how hot it actually feels when factoring for humidity. Prolonged exposure to a heat index above 80 degrees can lead to fatigue, as previously reported by USA TODAY. As it gets hotter, the risk continues to increase − potentially resulting in heat stroke or even death. Older adults, children, and outdoor workers are generally at higher risk of heat-related incidents. Search the heat index in your area Is your city getting hotter? It's possible! You can check the heat index forecast here to find out! What's the difference between temperature and heat index? The temperature is the actual air reading — what a thermometer records in the shade. The heat index, on the other hand, represents what it feels like to the human body when both temperature and humidity are factored in, according to the National Weather Service. When humidity is high, sweat doesn't evaporate as easily, making it harder for your body to cool down. That's why the heat index is often higher than the air temperature, and why it's used to gauge the risk of heat-related illness.

New users who download our updated app get a seven-day free trial. Hong Kong's forecaster has issued a 'very hot weather' warning, expecting temperatures to hit 33 degrees Celsius (91.4 Fahrenheit) on Thursday and sweltering conditions to continue on Friday and Saturday. The Hong Kong Observatory said that Tropical Storm Co-May, named after a type of coarse grass originating from Vietnam, was located within 800 km of the city and would linger over the northern part of Luzon, gradually intensifying later in the day and on Friday. But the forecaster also indicated the storm would then move towards the seas east of Taiwan, maintaining a distance of more than 600km from Hong Kong, posing a low direct threat to the territory. It issued a very hot weather warning at 6.45am, adding that showers triggered by high temperatures would also affect the region. 'A broad trough of low pressure will bring showers and thunderstorms to the central and northern parts of the South China Sea in the next few days,' the Observatory said.

Hong Kong axes flights, classes as Typhoon Wipha nears
Passengers stranded at Hong Kong airport as Typhoon Wipha grounds multiple flights. (EPA Images pic) HONG KONG : Hong Kong issued its third-highest tropical cyclone warning in the early hours of Sunday as Typhoon Wipha drew nearer, with authorities cancelling classes and grounding hundreds of flights. Wipha was located around 280km (175 miles) southeast of Hong Kong as of midnight (1600 GMT), according to Hong Kong's weather observatory. The observatory has hoisted the T8 warning signal, meaning that 'winds with mean speeds of 63kmh or more are expected'. The storm was expected to keep intensifying, moving across the northern part of the South China Sea and edging closer to the coast of China's Guangdong province. 'There will be frequent heavy squally showers and thunderstorms over the region. Seas will be high with swells,' the observatory added. China's Hainan and Guangdong provinces were also put on high alert, state news agency Xinhua reported Saturday. More than 250 flights servicing Hong Kong had been cancelled as of late Saturday, according to the website of the city's international airport. Hong Kong's Airport Authority asked travellers to prepare for 'significant flight cancellations or delays' and said that no passenger flights are expected to depart the city before Sunday noon. Authorities suspended Sunday's classes at all day schools and daycare centres. Bus services are expected to be halted until midday Sunday. Wipha brought heavy rains and flooding to the Philippines and two people have been reported missing, according to the country's national disaster risk reduction and management council.

Flooding possible as thunderstorms hit England's south
The Met Office has issued a yellow weather warning for thunderstorms across the south of the UK. The warning, active from 12.52pm until 5pm on Wednesday, covers Brighton and Hove, East Sussex, and Kent. Slow-moving heavy showers are expected, with 20-25mm of rain likely in under an hour, and up to 30-40mm possible over one to two hours in some locations. This rainfall could lead to surface water flooding and potential lightning strikes. The current wet spell follows a dry spring and three heatwaves, which left four regions of England in drought.
