Effects of Storms

Effects of Storms

Effects of Storms can be anything from the change in temperature to the damage in some cases - extreme destruction. Storms can impact people and property in many ways. Generally, the more severe the storms, the more the impact.

The media often report on stories such a Tropical Cyclone Yasi and Debbie and the impact of other storms such as trees through houses. Of course, a lot depends on the climate of the region.
In Europe and the North America, the effect of storms and weather can be from snow or ice! Snow can cause major disruptions to transports including roads and airport due to accidents or closures. Electricity supply failures can also occur

Approaching storms can also raise dust reducing visibility and eroding good top soil from agricultrual land.
Furthermore, Australia is a country prone to major bushfires which can destroy property, cause loss of livestock and also take lives..

Australia is a land of extremes and with droughts comes the floods. Major losses occur to property in terms of insurance values and loss of items runs into the tens of millions. This flood in Lismore certainly illustrates the impacts on the local community. Roads were also damaged in more recent floods: the dangers are certainly evident!

Some of the most intense efects of storms damage images come from tornadoes. Tornadoes can cause vehicles and even house to be relocated with even whole communities being destroyed. Greensburg suffered from its fate on the evening of the 4th May 2007. A 2.7km wide major tornado made a direct hit on the country township obliterating anything in its path!

Hailstorms near Luddenham 24th November 2017

Hailstorms Luddenham 24th November 2017

Higher resolution of the hailstorms Luddenham - pictures are provided here and brief chase report

After a very warm day, storm towers that were already developing spread further northeast towards the Sydney basin. As the sea breeze ventured towards the west, north west winds from outflow of previous storms over the mountains and of course outflow from cells near Badgerys Creek, a triple point allowed for sufficient convergence promoting the development of another storm. This rapidly dumped very heavy rain and hailstones.

Just was lucky for a change and only had to chase 10 minutes away from school/work. Parked and time-lapsed at Luddenham and watched as the new base developed overhead.

This would dump and form a black core on radar which produced hail to under 2cm (perhaps up to 1.5cm based on hits on the car) as we passed through and then filmed pea sized hailstones. Traffic was horrendous so the new core further north was virtually impossible to get through with the storm collapsing. Thanks for the drive from Rodney once again.

Severe Sydney Storms hits St Clair 22nd March 2017

Some severe storms hit St Clair during the afternoon with hail, very heavy rain and some powerful winds causing blackouts and traffic chaos. The storms developed over the Blue Mountains southwest of Sydney and moved rather quickly towards the Sydney region. A severe thunderstorm warning was released by the Bureau of Meteorology for storm winds large hailstones and heavy rainfall. Although the hail size reached the severe threshold of 2cm in some suburbs, the more significant threat were the winds. The worst damage seem to occur in the suburb of Whalan with debris and trees also reported in Glendenning and St Clair. Downburst winds known as microbursts descend rapidly from thunderstorms and can sometimes accelerate and spread out at the surface. Winds of about 100km/h resulted in trees being felled and branches stripped from trees across the suburbs.

After a parched summer, the region was still saturated from heavy and persistent rainfall in previous weeks. Severe runoff was quite widespread and some roads underwater.

The storms moved towards the coast and seemed to weaken as they progressed northeast to Gosford and Newcastle.
