Skymet weather

First week of September disappointing for Bangalore

bangalore rain After observing some good amount of rainfall in the month of August, the twin cities of Karnataka, Bangalore and Mysore experience a lull for the initial nine days of September. Till the 9th of September, Bangalore has received only 11.3 mm of rain, while Mysore has observed a meagre 6.1 mm against the monthly average of 241 mm and 132 mm, respectively. Bangalore receives highest amount of rainfall in September.

Even though the region of south interior Karnataka has been receiving surplus rainfall, there has been a modest drop in the weather activity in these cities in the present month. Bangalore has observed scanty rains so far, except 8 mm of rain recorded on 8th September. Similar is the scenario with Mysore, which also gets good amount of rain during the month. However, both the cities have received excess rain till August.

According to Skymet Meteorology Division in India, the twin cities will not observe any significant rainfall in the coming days and it is highly unlikely that they will catch up with the monthly normal. Due to this, the maximum temperature is expected to rise marginally.

Bangalore is the heart of the Mysore plateau, situated at the height of 3000 ft. Due to its high elevation, Bangalore and Mysore normally enjoy pleasant weather conditions throughout the year, although occasional heat waves make summer little uncomfortable.

Though another system which formed in the Bay of Bengal has moved inland bringing heavy showers to central parts of India. As the low pressure of monsoon system formed over Odisha, Andhra Pradesh and adjoining Bay of Bengal moves inland, it leads to widespread heavy rains in parts of Odisha, Chhattisgarh, South of Chhattisgarh, Telangana and coastal Andhra Pradesh.

In Andhra Pradesh, Kalingapatnam received rain of 59 mm and Hyderabad received 22 mm of rain in the last 24 hours. Titlagarh in Odisha received heavy rain of 174 mm during last 24 hours.

Due to the proximity of water bodies – Bay of Bengal and Arabian Sea – to the track of monsoon system, moisture will continue to infuse and a spell of heavy rain cannot be ruled out.

In the next 48 hours, moderate to heavy rain showers will be seen in Madhya Pradesh, North Gujarat and Konkan Goa.

 

 

Flooding Concerns for Southeast Europe during weekend

europe CroppedAn area of low pressure that moved across Italy on Monday and Tuesday with showers will stall over southeast Europe till the weekend. Showers and thunderstorms will continue the risk for flooding from the east coast of Italy into the Balkans, Greece and Bulgaria.

Daily downpours have already soaked the region and more rainfall is on the way. From Tuesday night into Wednesday, the heaviest rain fell from Albania into northern Greece, Macedonia and southwest Bulgaria where local amounts exceeded 100 millimeters (4 inches).

Through Thursday, the low will stall over southeast Europe leading to continued showers and thunderstorms. Additional rainfall of 25-50 millimeters (1-2 inches) is expected with local amounts over 75 millimeters (3 inches). Flooding will be the greatest threat; however, areas that have rugged terrain could also experience mudslides. Many locations in southern Europe received above-average rainfall through August, which only increased the threat for flooding from this most recent rainfall. Valjevo, Serbia, for instance, reported over 200 percent of normal rainfall during the month, totaling 181 millimeters (7.13 inches).

On Friday, showers and thunderstorms had become less widespread; however, due to prior rainfall, flooding will still be a concern across the region. The storm will continue to weaken over the weekend, diminishing the threat of widespread flooding problems. However, the storm system will continue to produce scattered showers and thunderstorms over the same region which could lead to some isolated flooding in areas that experienced the heaviest rainfall earlier in the week.
