Birders are continuing to flock to Greystones in Co Wicklow after what is believed to be the first ever sighting of a Brown Booby in Ireland.

The large seabird is usually found fishing in tropical waters in the Gulf of Mexico and the Caribbean.

It was spotted yesterday afternoon in Greystones and has delighted birders by loitering at the beach today.

Niall Hatch from BirdWatch Ireland said: "It's a species that's supposed to be in the tropical Atlantic, where it's found in the West Indies and the Cape Verde islands.

Flood inundates villages in northwest Iran - roads to 50 cut off

FLOOD
Heavy rainfall caused flooding in dozens of cities and villages in Iran's northwestern province of Ardebil, forcing many families to leave their homes.

Roads to some 50 villages have been cut near Meshkinshahr, Ardebil Province, due to the heavy rain and flooding.

Necessary measures are underway to reopen the roadways to the areas.

Two villagers have gone missing after the flash floods and a search operation is underway.

A flooded stream in Daejeon has stopped passers-by as the city saw downpour on Monday that continued from a day before.
Some 200 millimeters of rain pounded South Korea's southern regions on Monday, leaving several people dead and causing traffic accidents, flooding and destruction of roads, houses and facilities, officials said.

According to the Korea Meteorological Administration (KMA), 277 mm of rain fell in Sancheong of South Gyeongsang Province for one day by 2 p.m., followed by 228 mm in Buan of North Jeolla Province, 210 mm in Geoje, west of Busan, 158.2 mm in Gwangju and 160.2 mm in Daejeon.

In the southeastern province of South Gyeongsang, the per-hour precipitation reached 30 mm, while southwestern coasts, Incheon and five Yellow Sea islands close to the North Korean border were put under a strong wind advisory, the agency said.

Heavy rain, extreme hailstorm leads to flooding in Gyumri, Armenia

hail
Streets and basements in Armenia's second-largest city of Gyumri were flooded after heavy rainfall and hailstorm on Monday.

The storm left roads and vehicles partially submerged, and traffic disruptions were also reported in other parts of the northwestern Shirak Province.

Vehicle and property damages were also reported across the region, with many experiencing power outages.

Mysterious new invasive algae smothering Hawaii's coral reefs

College of Charleston professor of biology Heather Spalding documents a mat of invasive-like algae at Pearl and Hermes Atoll. The alga has smothered all native algae and corals.
Hawaii is famous for a lot of things. Perfect waves and perfect weather, to name a few. Stunning views and crystal clear water to name a few more. One of the most famous things it is famous for, however, is its coral reefs. And according to a study in the journal PLOS One, those reefs could be in some serious trouble.

Back in 2016, survey cruises conducted by the National Oceanic and Atmospheric Administration (NOAA) picked up strange specimens of an undetermined red alga. It "rapidly attained alarming levels of benthic coverage at Pearl and Hermes Atoll, Papahānaumokuākea Marine National Monument, Hawaiʻi," which, in layman's terms, means it spread like wildfire in shallow shoreline waters. A few years later, they went back to have another look, and what they found was strange indeed.

"By 2019 the seaweed had covered large expanses on the northeast side of the atoll with mat-like, extensive growth of entangled thalli," the abstract from the study reads. "Specimens were analyzed using light microscopy and molecular analysis and were compared to morphological descriptions in the literature for closely related taxa. Light microscopy demonstrated that the specimens likely belonged to the rhodomelacean genus Chondria, yet comparisons to taxonomic literature revealed no morphological match."

In short, it appears that the alga is likely to be an unknown species. That's a problem, because the Papahānaumokuākea Marine National Monument is uninhabited, remote, and pristine — which makes it susceptible to invasive species like this one.

Big snow totals across the Snowy Mountains, Australia - nearly 40 inches in 24 hours

The freshies in Thredbo were best yesterday morning, the snow getting heavier as the day went on.
Well, that was an incredible 24 hours for the NSW resorts with 70-100cms of snow in a 24-hour period, the higher totals falling above 1800 metres, but there was also snow all the way down to Jindabyne and beyond.

The first snow fall came through on Sunday with a few centimetres during the day before things kicked in overnight, leaving 17cms on the deck outside my place in Thredbo Village and 40+cms on the mountain by yesterday morning.

The snow kept falling all day, dumping at times, before it finally eased at around 8pm last night and there's a few lingering snow showers today. The result is 100% of the terrain in the NSW resorts now has a good base and more lifts will open this week.

Incredible rare peek at Patagonia in winter, high pressure area bringing unusually cold temperatures

June 26, 2020

Patagonia, June 26, 2020.
In southern South America, clouds often rule the skies. But in June 2020, just the right weather patterns were in place to provide a rare, clear view of Patagonia in winter.

On June 26, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite acquired these images, skies were clear over nearly all of Patagonia, which spans more than 1 million square kilometers of the continent's southern end. Snow cover is visible from the western slopes of the Andes Mountains in Chile to the coastal lowlands in Argentina.

According to René Darío Garreaud, a professor at the University of Chile, it's unusual to see such a widespread cloud-free area over Patagonia. "The last time that I saw a completely clear image was in February 2019," he said. At that time, during the Southern Hemisphere's summer, the warm seasonal temperatures meant snow and ice were mostly limited to the spine of the Andes and the Patagonian icefields.

Japan hammered by record-breaking torrential rains and deadly floods, 3 inches of rain per hour - A metre in 3 days

A week of torrential rain pounded southwestern and central Japan, triggering severe flooding and landslides that have killed at least 68 people in the region. Kumamoto prefecture in Japan's southern island of Kyushu has been hardest hit, and over the weekend residents braced for more extreme weather. On Saturday some areas observed more than 80 millimeters of rainfall per hour and 1,000 mm over three consecutive days. Strong winds, lightning, and tornadoes were also added to the weather warning. The Ministry of Land reported 282 mudslide disasters across 27 prefectures with the largest number, 52, in Kumamoto prefecture.

Eastern and western Japan are on high alert for heavy 24-hour downpours with a risk that rivers in Iwate and Aomori could overflow. New mudslide warnings have also been issued for Kyushu as past rain loosens the ground and damaged river levees inundate low-lying areas.

Hundreds of thousands of people have been affected by floodwaters and landslides following incessant rainfall in the region.
Six more people have died in floods and mudslides in northeastern India's Assam state, officials said Tuesday, taking the death toll to 77 from more than two weeks of heavy rains that caused one of Asia's largest rivers to overflow.

The Brahmaputra River continued to wreak havoc, displacing more than 2 million people, the officials said. Vast tracts were still underwater with 26 of the state's 33 districts badly affected.

M.S. Mannivanan, head of the State Disaster Management Authority, said rescue and relief operations were underway.

"We have 40 teams of the State Disaster Response Force in the worst-hit areas and the army also is on standby," Mannivanan said.
