A sandstorm that lasted 20 minutes has caused significant damage to houses in the town of Catanduva in Sao Paulo, Brazil (6th). Sandstorms also blanketed other cities and towns in the state causing the sky to turn different shades of orange and brown.
The skylines across the state changed color as strong winds combined with a drought that has hit the country, lifting surface soil and dust into the atmosphere.
A severe hailstorm hit the Bolivian town of Taija, leaving impressive amounts of hail on the streets (31st). Parts of the city were covered in up to 60 cm of hail.
More than 1.76 million people have been affected by severe flooding in China's northern Shanxi province, according to local media (10th). Torrential rain last week lead to houses collapsing and triggered landslides across more than 70 districts and
cities in the province. China's Meteorological Administration told local media that heavy and prolonged rainfall and storms are hampering rescue efforts. Shanxi is also home to a number of ancient monuments which are at major risk from the severe
rainfall. Authorities told the Xinhua news agency that more than 120,000 people have been urgently transferred and resettled, and that 17,000 homes have collapsed across Shanxi province. Shanxi's provincial capital Taiyuan saw average rainfall of around
185.6 mm last week, compared to the 25 mm monthly average during 1981-2010.
The island of Corfu was declared in "state of emergency" later in the day after torrential rains from storm Ballos flooded homes and businesses, destroyed infrastructure, agriculture and livestock, thus endangering human lives (14th). 69 people in total
had to be evacuated with boats or helicopters as they were trapped in the floods. One person was killed on the island of Evia after he was carried away by the rushing water during the storm. A month's rainfall was reported to have fallen in 24 hours
during the storm.
At least 26 people have been killed in floods in southern India after heavy rains caused rivers to overflow, cutting off towns and villages (11th-18th). There are fears the death toll could rise further as many people are missing. Several houses were
washed away and people became trapped in the district of Kottayam in Kerala state. Kottayam and Idukki are two of the worst affected districts in the state, where days of heavy rainfall have caused deadly landslides. Swollen rivers have also washed away
bridges connecting many small villages. On Monday, a number of dams across Kerala state were opened to reduce the risk of dangerous overflows. The government had earlier said the decision on which dams to open would be made by an expert committee. "
District collectors will be notified hours before opening the dams so that local people have enough time to evacuate," said the office of Kerala's chief minister, Pinarayi Vijayan. In a 24-hour period to October 12, Karipur recorded 255 mm of rain,
Kozhikode 216 mm, and Kannur 166 mm. The rain continued across the state, worsening over the last 2 days with Kochi recording 129 mm of rain in 24 hours to 17 October and Valparai 101 mm in 24 hours to 18 October. According to the India Meteorological
Department, the heavy rains were caused by a low pressure area over the SE Arabian Sea and Kerala.
At least 46 people have died in flash floods triggered by heavy rains in the northern Indian state of Uttarakhand (19th). Images and videos from the state show flooded roads, submerged homes and fallen bridges. Experts say the Himalayan state, a popular
tourist spot, is seeing the effects of both climate change and rampant construction. Floods have also ravaged the southern state of Kerala, where at least 26 people have died in recent days. Both states have recorded excessive rainfall this year,
according to data from India's weather department. Kerala, for instance, recorded 453.5 mm rainfall as opposed to the 192.7 mm that is considered normal during this time of the year. According to India Meteorological Department (IMD) data, the districts
that observed heavy to extremely heavy rainfall were Champawat, Nainital, Udham Singh Nagar, Pithoragarh, Bageshwar, Almora, Pauri and Chamoli from 8.30 a.m. on Monday till 8.30 a.m. on Tuesday. There were several reports where people called the rain "
multiple cloudbursts". But the IMD terms rainfall of 100 mm or above in just one hour as a cloudburst. The previous records of 24-hour rainfall in Uttarakhand was held by Pant Nagar that received 228 mm rainfall on 10 July 1990, but was now broken by the
current 403.2 mm rainfall. The observatory has records since 25 May 1962, when it was established there, IMD Dehradun data said. Similarly, at Mukteshwar, where the observatory was established on 1 May 1897, the previous record was of 254.5 mm rainfall
on 18 September 1914, was broken by recent fall of 340.8 mm of rainfall.

up to 125 mm of rain by 1100 LT on the 26th. Central Park in New York City received 68 mm of rain by 1300 LT while Islip on Long Island received 66 mm. As the storm continued intensifying, the number of customers without power in Massachusetts rose to

Hurricane Sam finally weakened below major hurricane strength on Sunday morning (3rd), ending a remarkable 7.75-day odyssey across the central Atlantic as one of the longest-lived major hurricanes on record. According to Phil Klotzbach of Colorado State
University, Sam is tied with Hurricane Edouard of 1996 for fourth-most consecutive days as an Atlantic major hurricane since the satellite era began in 1966. Sam is also in the top-ten list of Atlantic hurricanes for the length of time at category 4
strength. Sam's long life as a major hurricane was enabled by its relatively slow forward speed, avoidance of land areas, and warmer-than-average ocean waters.
At least 13 people have been killed after tropical cyclone Shaheen battered parts of Oman and Iran (3rd-4th). There was widespread flooding along Oman's northern coast as the storm made landfall on Sunday, bringing heavy rain and winds of up to 150 km/h.

It is rare for storms of this power to hit Oman's northern Arabian Sea coast. Authorities said 369 mm of rain fell on al-Khaboura, north-west of Oman's capital city, Muscat, while more than 200 mm was recorded in Muscat itself. The average October
rainfall for Muscat is 0.8 mm, and the average yearly rainfall is 89.7 mm. Shaheen's high winds also caused waves of up to 10 m along the coast.
Another tropical storm affected storm-weary Philippines as the country received a devastating blow from Tropical Storm Kompasu (11th). As a result of Kompasu, five people were killed in flash floods in the Palawan Province while four others were killed
