By the night of the December 23, a low-level circulation developed in the system, located to the south of the deep convection. This means that there is more than a 20% chance of potentially-damaging wind speeds in your project area in the next 10 years. A red alert has been issued for Northern Sri Lanka as Cyclone Nivar approaches. Last week, a more powerful cyclone skirted northern Sri Lanka but hit Tamil Nadu with full force, uprooting trees and delivering 30 centimetres (12 inches) of rain in some areas. There is no cyclone or Tsunamithreat to Sri Lanka at present. Other forms of debris are associated with severe rains and flooding that often accompanies cyclones. A safe room must also be built to withstand flying debris even when the rest of the building is damaged or destroyed. Be sure to review the ThinkHazard! Strong winds damaged or destroyed around 83,000 houses across the country, including 2,000 houses destroyed in Kinnia and 6,600 in Trincomalee. The most important construction measures to minimize wind damage to a roof include: proper installation of plywood sheathing, bracing of roof trusses, and use of hurricane straps. Independent wireless communication (e.g., VHF) radio may be a cost-efficient option for communications redundancy and prove vital in a time of crisis. It’s imperative to plan in advance for all aspects of a catastrophic wind event. Debris collection and removal can be extremely costly, and recent experience has shown debris removal is often more costly than direct physical damage to the building itself. The data set used to classify the hazard in this area is not publicly available to view or download due to licensing restrictions. After turning west-northwestward, the storm struck southern India near Kanyakumari on December 28 with winds of 45 mph (70 km/h), with minimal convection due to land interaction and increased wind shear. [2] It rapidly weakened to tropical depression status over land, degenerating into a remnant low later that day. [4] While crossing the country, the cyclone dropped between 4 and 8 inches (100 to 200 mm) of precipitation, compounding the effects of severe monsoonal flooding from the previous month. An intense cyclone can bring torrential rains and have embedded severe thunderstorms that are accompanied by tornadoes. 36/00 Situation Report No. [3] Later that day, the organization of the system degraded slightly, though it quickly reorganized. Regardless of whether the risk has changed, experts can propose long-term mitigation strategies, methods of disaster preparedness and response, and the value of insurance given the expected risk levels. Wednesday, December 2, 2020 - 01:02. Of these, only two have been formed in the Arabian Sea and made landfall in either western or northwestern coastlines of the country; the rest have all been formed in the Bay of Bengal and made landfall on the north and east coasts. The present hazard level in areas currently affected by tropical cyclones may increase in the long-term. But more accurate forecasting and the timely evacuation of several hundred thousand people were credited with keeping the number of people reported killed to three, a fraction of the death tolls in previous years. The 2000 Sri Lanka cyclone (IMD designation: BOB 06 JTWC designation: 04B) was the strongest tropical cyclone to strike Sri Lanka since 1978. At least nine people died as a result of the cyclone. Well-marked low over SE BOB and can concentrate into a depression next day or so. [3] Located within an area of weak vertical wind shear, the system steadily organized, and after initially remaining nearly stationary it began to move slowly westward. Climate change impact: Global average tropical cyclone wind speed and rainfall is likely to increase in the future, and the global average frequency of tropical cyclones is likely to decrease or remain unchanged. Bring in unsecured outdoor furniture and other property. To kick-start the operation, the Federation released about $61,000 (2000 USD ($90.6 thousand 2021 USD, $100 thousand in 2000 CHF)) within a few hours of the cyclone making landfall. • To learn more about the risks, engage with qualified meteorological and engineering experts with the goals of: Shut off supply lines to flammable liquids, combustible liquids and gas at their source. Clean floor drains, catch basins, and pumps to ensure proper drainage. water, electricity, transportation networks). It moved westward, and quickly strengthened under favorable conditions to reach top wind speeds of 75 mph (120 km/h). The cyclone hit eastern Sri Lanka at peak strength, then weakened slightly while crossing the island before making landfall over southern India on December 28. 2. • After construction is complete, wind experts can evaluate all scientific literature that has been published since construction began to determine if the risk is even higher than previously suspected and also suggest additional steps to increase resilience. During the design and construction plan review phases, wind engineers will review the latest available literature and data to confirm that your project is exposed to the dangers of cyclone winds, and propose mitigation measures to protect your assets. In less than a week after Cyclone Nivar swept past Tamil Nadu and Andhra Pradesh, another cyclone started to brew over the Bay of Bengal.
