The temperatures in the sub continent show no signs of the winter lows. The days and nights are still above the normal. Another WD is awaited for the actual winter to arrive in the region. The IMD maps above show the extent of the above normal temperatures.

Meanwhile the cyclonic storm "Rashmi" weakened and after passing through the north-eastern states of India, crossed into Tibet region.A massive snowstorm followed.
The snowstorm event was attributed to "Rashmi" which developed over the Bay of Bengal and drifted north. Heavy rain associated with the cyclone quickly turned into heavy snow across the Tibetan region as it collided with a cold air mass. Although heavy snow is not an uncommon event in Tibet, a snowstorm this severe was fairly unusual this early in the season.
Heavy snow fell for more than 36 consecutive hours earlier in the week averaging snow coverage of 1.5 meters, with drifts up to three meters in places. Many people were either frozen to death or crushed by buildings which collapsed from the sheer weight of the snow.

Meanwhile,there is a weak sign of an easterly wave bringing some rain in TN and south AP from the 5th.The rains are expected in TN for about 3/4 days, before drying out again. ECMRWF expects the next low in the bat around the 16th. Not much rain before that.
