RT @Geetha_Anand: Heavenly rain @ bangalore with thunder and lightning!! Just awesome, I say. Just Kewl!! Chilling out :)
RT @vpnmenon: Its raining here in Bangalore... Temperature is down....
This video shows the past 6 hrs satellite images loop.
From 12:30pm IST to 6:30 pm IST.
Very heavy electric (Thunder) showers over SOuth Karnataka, South Andhra, Central Andhra and even into South-west Orissa.
Showery activity can also be traced over Kerala western ghats.
For the past 24 hrs the South-west Bay, South of Srilanka and Gulf of mannar was very active with lots of showery activity and it continues to be like that at present (6:30pm) as well.
South extreme of Tamilnadu and Kerala was under high cloud cover from 12pm.. but no reports of rain yet.
Now Some isolated showers again over South & Interior Karnataka.
Fresh western disturbance is likely to affect western Himalayan region from tomorrow
Trough runs from north Karnataka to Tamilnadu at 0.9 km above mean sea level with cyclonic circulation over Karnataka and neighbourhood.
Rainfall on 13-Apr, Dibrugarh-6, Haflong and Udhagamandlam-3 , Goalpara, Gangtok, Kailashahar, Cooch-Bihar, Itanagar, Cherrapunji, Silchar 2
Heat wave conditions over north Gujarat, Chhattisgarh, interior Orissa, Jharkhand and coastal Orissa.
On 13-Apr, highest maximum temperature of 45.5°C was recorded at Hirakud (Orissa).
IMD:: Monsoon forecast may be declared on 20 April
This topographic map of the area shows major faults (red lines), as well as the epicenter of the 7.2-magnitude quake (darkest circle) and all 4.0-or-larger aftershocks that occurred through 19:25 UTC on April 5 (12:25 p.m. U.S. Pacific Time). The topography is from digital elevation data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite.
According to the U.S. Geological Survey (USGS), the Pacific plate moves northwest with respect to the North America plate at about 45 millimeters per year at the latitude where the quake occurred. The area is about 60 kilometers (40 miles) south of the Mexico-United States border. The USGS describes the geologic setting as “a series of northwest-trending strike-slip (transform) faults that are separated by pull-apart basins.”
These basins are evident in the topographic image. The larger structure is the Salton Trough, a depression that stretches from the Gulf of California, through the modern Colorado River Delta, and northwestward into California as far as the Salton Sea. A line of mountains separates the larger eastern part of the trough (called the Imperial Valley in the United States and the Mexicali Valley in Mexico) from the smaller Maguata Basin (also called the Laguna Salada Basin) to the west.
The USGS reported that the location of the Baja quake was consistent with a rupture of the southeastern end of the Laguna Salada Fault, but said that a definite location would require additional information. Aftershocks extended along the fault system in both directions.
The image shows the concentration of particles in the atmosphere (aerosols) during March 2010. A dark brown plume extends west from Africa where thick dust blew over the ocean. Dark brown patches also cover parts of China and Southeast Asia where aerosols clouded the sky. Dust contributed to the aerosols in the north, but smoke is the likely culprit for high aerosols in the south. Fires burned extensively in Southeast Asia through March, veiling the region in a pall of smoke.
This image was made from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite throughout March 2010. Areas where the sensor couldn’t collect aerosol measurements are gray. Since aerosols such as dust, smoke, and haze are often pale, it is difficult to record concentrations over bright surfaces like the deserts of Africa, Arabia, and Asia or the snow-covered landscape of North America, Europe, Asia, and Antarctica. Other gray areas show where clouds consistently blocked the sensor’s view of aerosols.
Chennai - Will touch a max of 36 deg C and then slowly go down. "Happy Tamil New Year"
Sea zone, South-west and south-east of Srilanka is very active with huge thunder storms for the past 48 hrs.. Now also no different.
Yesterday at around 11:30pm, there was a thunder storm swept across North Bihar and North W.Bengal.
