A hurricane local statement is a weather statement produced by the local weather forecast office and distributed to the public in the area affected by a hurricane. It details how the storm will affect the area in which it hits. This statement can help you to make necessary preparations for the hurricane’s arrival. Here are some things you should know:
STORM SURGE AND COASTAL FLOODING IMPACTS
The STORM SURGE and coastal flooding impacts of climate change are largely unknown, but their impact on human infrastructure is significant. The amount of rainfall, the duration of the storm, and the intensity of the storm surge all affect coastal flooding. The latter, however, is the more destructive of the two. Coastal flooding occurs when sustained heavy rain does not drain away from the coast. Meanwhile, storm surges drag seawater up and over the coast. As a result, the effects of coastal flooding are even more devastating if several storms happen close together.
The storm surge and coastal flooding impacts of tropical cyclones differ widely. Storm surge is the high water above the local tide levels. It is caused by the hurricane’s winds and low atmospheric pressure. Tropical cyclones produce higher storm surges and flooding because of their greater intensity and longer duration. On the other hand, ETCs can cause significant wind damage and flood waters, as they move slowly inland.
A STORM APPROACHES – Read the STORM APPROACHES local Hurricane Statement to make preparations. This dangerous storm may produce tornadoes, heavy rain, and flash flooding. These conditions can wreak havoc on your life. If you live in or near the affected area, you’ll want to prepare in advance. Below are some tips to help you prepare for this storm.
STORM IMPACTS ON ROADS
As the sea level rises and the frequency of storms increases, storm impacts on roadways are also predicted to increase. Major impacts can include coastal flooding, transportation disruptions, and mudslides. Approximately $672 million will be spent cleaning up storm debris, and the Mississippi Department of Transportation anticipates spending over $1 billion. Increased flooding will cause road and bridge closures. Increased erosion and damage to coastal wetlands may further hamper travel and transportation.
The impacts of flooding and weather are often underestimated. Typical approaches to measuring floodwater impacts fail to capture the complex interactions between floodwater and the transport system. They typically assume the road is closed or fully blocked, and neglect to account for differences in road speeds and floodwater depths. The lack of detailed information on floodwater-induced road and transport impacts makes it impossible to properly plan and allocate scarce resources. Fortunately, there are some ways to measure floodwater impacts on roads and assess how they can be mitigated.
TORNADO IMPACTS in OUTER RAINBANDS
The goal of the study is to document the structure of multiple offshore convective cells within the outer TC rainbands. The researchers will also determine the frequency of offshore supercells and determine significant differences between tornadic and non-tornadic soundings in landfalling TC. The researchers have received funding from the Federal Alliance for Home Safety and support from NOAA’s Hurricane Research Division. The study was published in the Monthly Weather Review.
The compact spatial distributions of tornadoes are revealed when comparing their occurrences to the five selected stages of the associated tropical cyclone. The best relationships for location within the parent cyclone are obtained from true azimuth, which is superior to the orientation obtained from the tropical cyclone’s track. Once extratropical tornadoes are eliminated, the compact pattern is located in the northeastern sector, with its locations defined within a specified normalized distance from the centre of the parent cyclone. Extratropical tornadoes, on the other hand, are widely distributed within the southern quadrants of the parent cyclone.
