Flash floods that struck two provinces in Indonesia this week have killed at least 19 people, according to disaster mitigation officials, with operations under way to search for the missing.

Torrential rains beginning on Monday caused flooding and landslides on the tourist island of Bali and in East Nusa Tenggara province.

Indonesian President Prabowo Subianto ordered his aides to accelerate the handling of the aftermath of the deadly flooding, locate the missing and deliver basic needs to displaced residents, Antara state news agency reported on Thursday.

The National Disaster Mitigation Agency, BNPB, reported that 400 to 600 personnel from various institutions had been deployed to search for the missing and clear debris.

Rain caused rivers to burst their banks, tearing through nine cities and districts on Bali. Mud, rocks and trees tumbled onto mountainside hamlets and rising rivers submerged at least 120 neighbourhoods, resulting in a dozen landslides in several places, BNPB spokesperson Abdul Muhari said in a statement.

The Japan Meteorological Agency says a tornado that swept through a swath of Shizuoka Prefecture, central Japan, last Friday is likely to have been one of the strongest ever recorded in the country.

The agency classified a strong gust of wind that hit areas stretching from the city of Makinohara to the town of Yoshida amid an approaching tropical storm as a tornado, after inspecting the extent of damage it left.

It estimated that the wind gusted to approximately 270 kilometers per hour -- powerful enough to deform the exterior walls of a steel-frame building.

The officials rated the intensity of the tornado as a three on the Japanese Enhanced Fujita Scale of zero to five.

Hurricane Kiko is closing in on Hawaii, where residents are preparing for life-threatening rip currents and towering waves up to 15 feet.

The storm is currently moving northwest at 14 mph, and the National Hurricane Center (NHC) said it should maintain that course over the next few days.

On this track, Kiko is expected to pass north of the main Hawaiian Islands on Tuesday and Wednesday.

Spaghetti models show multiple potential paths for the storm, but the most likely track takes it near or just south of the Big Island before moving northwest across the central Pacific.

Comment: From The Weather Channel:
While Hurricane Kiko continues to weaken as it passes north of Hawaii, the state will still experience much larger swells, dangerous rip currents and possibly other impacts this week.

Despite Kiko's weakening trend, swells generated by the storm are beginning to reach Hawaii, causing life-threatening surf and rip currents, especially along east-facing beaches.

The threat for large swells and rip currents will remain in place for the islands through mid-week, especially for north-facing beaches, as Kiko passes to the north.

We could see increased rainfall through the week and some stronger gusts over higher elevations and exposed coastal areas, however, dangerous ocean conditions will be the main threat with this particular storm.

Tens of thousands of people have been evacuated as Typhoon Tapah has made landfall in southern China, causing flight disruptions and school closures.

State broadcaster CCTV said the storm made landfall on Monday morning in the city of Taishan in Guangdong province, unleashing powerful winds and torrential rain.

The Guangdong Meteorological Bureau raised a yellow alert, the third highest in China's four-tier warning system, and forecast thunderstorms and gale-force winds.

Authorities said an estimated 60,000 people have been evacuated across southern China before the storm came ashore with maximum winds of 108 kilometres per hour (67 miles per hour).

Guangdong's Emergency Management Department ordered the suspension of all outdoor activities and closed recreational areas like parks and beaches. Schools were also closed.

Guangdong has been hit by 16 typhoons this year. Tapah is expected to move northwest, gradually losing power until it exits the province.

San Antonio police found two bodies along the Salado Creek on Monday afternoon while searching through piles of debris.
The bodies of two people were found Monday after a San Antonio creek flooded Sunday night.

San Antonio police said friends of the victims reported them missing. One of the bodies was later found by them and the other was found by authorities that had responded to the scene.

The victims, only identified as a man and woman, were found in Salado Creek along with lots of debris that washed downstream during flooding on Sunday night, according to police.

A third person who had been reported missing was later found safe.

About 2 inches of rain was reported at San Antonio International Airport on Sunday night, according to the National Weather Service. A Flash Flood Warning was issued for the north side of San Antonio at about 7:15 p.m. CT.

The deaths come nearly two months after catastrophic flooding in central Texas during the July 4th holiday resulted in nearly 140 deaths. Most of those happened at Camp Mystic, an all-girls Christian retreat near the Guadalupe River in Kerr County.

Supercell storm leaves 200-kilometer-long hail scar across Canada's "Hailstorm Alley" on August 24

A destructive hailstorm has literally made its mark on southern Alberta, Canada, after pummeling the region with golf ball-sized hailstones, leaving a 200-kilometer-long, 15-kilometer-wide (124-mile-long, 9-mile-wide) "scar" across the landscape that's been captured in satellite images.

Shared by NASA Earth Observatory, a satellite image taken on August 19 shows all looking well just southeast of Calgary, with an untouched mix of farmland and green areas. Then, on the night of August 20, what Environment and Climate Change Canada (ECCC) Weather Alberta described as a "strong supercell thunderstorm" swept across southern Alberta in just 4 hours.

Alongside gusts reaching over 130 kilometers per hour (81 miles per hour), the storm brought with it a blitz of massive hailstones.

Hail is a type of precipitation (the fancy name for water falling from the sky) made up of solid ice, formed when a thunderstorm's updraft (a rising column of warm, moist air) carries up raindrops to cooler parts of the atmosphere, where they freeze. Once the weight of the hail can no longer be supported by the storm's updraft, it falls.
