Two tropical storms quickly followed Hurricane Fiona, causing deadly flooding in the Caribbean and Strongest hurricane on record to make landfall in Canada. Typhoon Nanmadol, has displaced 9 million people in Japan.
Fingerprints of climate change
The World Meteorological Organization has reminded that Climate change is expected to increase the prevalence of major tropical cyclones worldwide, and to increase the heavy rainfall associated with these events.
Meanwhile, sea level rise and coastal development are also exacerbating the impact of coastal flooding.
“The human and socioeconomic impacts of these tornadoes will be felt for many years,” warned Cyrille Honoré. WMO Branch Manager of Public Service and Disaster Risk Reduction.
Hurricane Ian made landfall in Cuba on September 27 as a Category 3 hurricane, with sustained winds of 205 km/h and stronger gusts leading to flash floods and mudslides.
It is estimated that more than three million people have been affectedThe UN Resident Coordinator’s Office announced.
According to WMO, Cuban President Miguel Díaz Canel said the damage caused by Ian could be significant, even though there are only preliminary assessments.
There were no reports of casualties. BuThere was severe damage to infrastructure, housing, agriculture and telecommunications, with power reported lost to the entire country. Pinar del Río, the worst-affected province, produces 75% of the country’s tobacco – Cuba’s main export – and about 40% of the country’s beans.
Florida is on high alert
Ian is strengthening rapidly and is now a very strong Category 4 hurricane (maximum sustained winds near 155 mph (250 km/h) with stronger gusts). It is expected to maintain this magnitude.
Ian was the first hurricane to make landfall in the continental United States this season.
The US National Weather Service has warned of catastrophic wind damage near the Ian core as it moves inland and storm surge and catastrophic flooding threatens life.
According to forecasts of experts, the combination of high tides and tides will cause dry areas near the coast to be flooded as rising water moves inland from the coast. Water can reach 12 to 16 feet (3.5 to 4.8 meters) in the worst-affected areas.
Heavy rainfall will spread across central and northern Florida through Thursday as it is forecast to slow its motion. Ian is forecast to approach parts of the Southeastern United States this weekend and this weekend (October 1-2).
Catastrophic flooding is expected across parts of central Florida with significant flooding in, north Florida, southeastern Georgia and coastal South Carolina.
“Ian poses a particular threat because of its size, power, and its landfall in a densely populated, low-lying area.WMO warned.
Meanwhile, in the eastern hemisphere, Typhoon Noruin the Philippines known as Karding, made landfall in the northeastern part of the Philippines on September 25 as a “super typhoon” with sustained winds of 195 km/h (121 mph) before tracking over the main island of Luzon on September 25.
More than two million people live in the worst-affected areasaccording to a disaster analysis, and nearly 430,000 people are directly affected. Although the mobilization time was relatively short, thousands of people were successfully evacuated, limiting the loss of life.
From September 26-27, Typhoon Noru entered Vietnam and strengthened once again.
The importance of early warning
WMO emphasizes that accurate early warnings and coordinated early action is proving the key to limiting casualties during extreme weather events such as Hurricanes Ian, Fiona and Thyphoon Noru.
WMO Secretary-General GS Petteri Taalas said: “It is more important than ever that we scale our action on early warning systems to build resilience to current climate risks. and the future in vulnerable communities”.
