Amber warning for heavy rain in east and south east
The Met Office alert - which is the second highest level - for Antrim, Down, and Armagh lasts from 23:00 BST on Sunday until 08:00 on Monday.
It comes in the middle of a yellow warning for the same counties which runs from 18:00 BST on Sunday until 18:00 BST on Monday.
Some areas could see between 50-75 mm of rain in a short amount of time, with a risk of flash floods.

The Met Office has said there will probably be difficult driving conditions as well as fast flowing or deep flood water likely to cause danger to life.
It has warned that homes and businesses may face flooding while some communities could be cut off by flooded roads.
The Met Office added that power cuts and loss of other services to homes and business businesses are likely.
The warning follows an earlier alert for thunderstorms for western counties of Northern Ireland on Sunday, which expired at 20:00 BST.

Extreme rain events are becoming more common in the Chicago area as the climate warms
Extreme rainfall events in Chicago, including two observed this summer, are becoming more common as the climate warms. Very small, localized thunderstorms brought intense rains to parts of Chicago on both July 8 and July 25. While data analysis of the more recent July rainfall event is ongoing, National Weather Service Senior Service Hydrologist Scott Lincoln tells CBS News Chicago that the 5 inches of rain that fell in less than three hours July 8 only has a 0.2% chance of happening in a given year. This would once have been referred to as a 1-in-500 year rainfall event, but the NWS now avoids that phrasing since there is no guarantee it will be another 500 years before it happens again. Late in the evening on July 8, a very localized, torrential thunderstorm sat over portions of central Cook County west of the Loop on the Eisenhower Expressway. Parts of the Near West Side, North Lawndale, the United Center, West Garfield Park and East Garfield Park experienced extreme rainfall, with one unofficial rain gauge tallying 5.39 inches in just two hours. "Comparing this event to our record of extreme rainfall events impacting the Chicago area since 1950 indicates that this is among the smallest recorded extreme rainfall events over that period, covering only an approximately three square mile area," Lincoln said. As global climate change warms Chicago area temperatures, it is leading to heavier rainfall events. For every one degree of warming, the atmosphere holds 4% more moisture. The heaviest rain events in the Great Lakes region have gotten 45% heavier since 1958, according to Climate Central. This is impacting Chicago's water infrastructure and flooding basements more often. "As of July 8, 2025, the 2020s decade has had four extreme rainfall events in central Cook County," Lincoln said. "Compared to the the 1950s, 2000s, and 2010s which each had two known extreme rainfall events within that same area." Lincoln noted rain gauge observations were not as widespread prior to the 1990s, potentially affecting historical data collection. "Multiple lines of evidence suggest that the threshold for 'extreme rainfall' in the Chicago area is changing," Lincoln said. "Analysis of daily rainfall in Chicago indicated that 'extreme' 1-day rainfall early in Chicago's history (1871-1930) was approximately 6 inches, while this value increased to just over 8 inches in more recent times (1961-2020)." More detailed studies of rainfall frequency indicate a heavy rain event that has a 1% chance of occurring in a given year — once called a 1-in-100 year event — has gotten heavier. A NOAA publication indicated a 100-year event was 5.6 inches of rain in the late 1950s. An Illinois State Water Survey publication shows it has increased to 8.6 inches as of the late 2010s.

20 counties in England set to escape 33C heatwave arriving in August
The fourth heatwave of the summer could be arriving next month as weather maps turn red. As we enter the second full week of August, temperatures are set to reach the low-30s. Heatwave conditions could take place between August 12 and 14, with temperatures reaching the 25C threshold and above. READ MORE: Met Office thunderstorm warning issued for 17 counties in England Get breaking news on BirminghamLive WhatsApp, click the link to join However not all of England could sizzle when the hot weather arrives. A total of 20 counties could escape the heatwave. Although the mercury could surpass 25C during that period, it's not set to remain at that level over three consecutive days, according to WX Charts. Temperatures are forecast to reach 32C in the West Midlands on Wednesday, August 13, however things are set to cool off the following day. The following counties could miss out on a heatwave conditions: West Midlands, Staffordshire, Shropshire, Herefordshire, Derbyshire, Nottinghamshire, Cornwall, Devon, Cheshire, Merseyside, Greater Manchester, South Yorkshire, West Yorkshire, North Yorkshire, East Riding of Yorkshire, Lancashire, Cumbria, Durham, Northumberland and Tyne & Wear. In its long-range forecast from August 4 to August 13, the Met Office said: "Early next week there is the potential for an unseasonably deep area of low pressure to affect the UK, which would bring widely windy and wet weather, especially for the west or northwest of the UK. "The forecast around this is rather uncertain, however, and it is also possible that this will turn into a less windy but still wet spell further south. "Following this, a continuation of the broadly changeable pattern is expected, with spells of rain or showers, some drier, brighter interludes and temperatures mainly near average. "As we move towards mid-month, there is an increased chance of high pressure becoming more dominant, leading to drier, warmer and more settled conditions becoming more widespread."

Where heavy rain may be a problem across the U.S. this week
A month full of downpours will end the way it started: with a chance for more flooding across the country. Pockets of heavy rain are possible, scattered about the Lower 48 this week. Flood watches were in effect Wednesday across the High Plains of Colorado and New Mexico, Iowa and Illinois, and southeast Montana. On Thursday, heavy rains could spread to the Acela corridor along Interstate 95 between Washington and New York City. On Wednesday, there were several areas at risk for flooding. On Thursday, a frontal boundary sagging southeast through the Mid-Atlantic and New York City tri-state area could pose some urban flood concerns. That will spark scattered to numerous thunderstorms in the afternoon, presenting a marginal risk for severe weather. High-resolution weather models suggest rainfall rates of 2 to 3 inches per hour are possible in the heaviest downpours. A few locales could receive 3 to 5 inches throughout the evening hours. That could spawn some flooding. The same frontal boundary will sag into the Carolinas on Friday, leading to a slight risk of flash flooding and excessive rainfall. A couple totals of 2 to 4 inches are possible. It's worth noting that, due to the scattered nature of summertime storms, some areas won't see much rain at all — whereas others may end up with more substantial totals. There have been a remarkable 2,285 reports of flooding across 47 states and D.C. so far this July. A nearly constant flow of moisture from the tropics has been harnessed by thunderstorm complexes, fronts and the remnants of tropical storms, leading to several deadly and destructive floods. The amount of moisture pulsing across the country's skies has also been at record-high levels — providing extra fuel for strengthening storms. This is part of an ongoing global trend toward a more vaporous atmosphere, a part of climate change that some researchers say isn't getting enough attention. Flood risks will continue across the Southeast into the weekend, while cooler, drier air ushers a break from downpours for the Midwest and Northeast.
