Features of South West Monsoon Withdrawal and the advance of the North East Monsoon:

This note is not a forecast nor a quantum estimate. It is just how to begin a Monsoon Watch for the NEM.
In the very initail para, we begin with the basic fact of the Monsoon origins. SWM has its origin around the Mascarene Highs off Madagascar, and the NEM has its origin round a large anticyclone over Siberia.

However, coming to the advances of these systems, the mode of setting of the 2 monsoons differ. The onset of SWM is well defined, and follows progressively Northwards.This can be monitored quite accurately on weather charts.
On the other hand the onset of the NEM is not clearly defined. In fact, in some years, there has been no clear indication between the withdrawal of the SWM in peninsula India and the onset of the NEM.

I would, on the above point, normally hesitate to actually present or believe a "normal date" for the onset of the NEM in the Southern States.

Krakatoa - Fresh Lava Flows

Although most of Krakatau disappeared in the gigantic eruption of 1883, the volcano lives on in Anak Krakatau, or “Child of Krakatau.” Anak Krakatau (also known as Krakatoa) emerged from the water of Indonesia’s Sunda Strait in 1927, and has erupted sporadically ever since. According to Antara News (the official news agency of Indonesia), a series of lava fountains and ash emissions began in early September 2012, accompanied by volcanic tremors.
This natural-color satellite image shows fresh lava flows descending the southeastern flank of Anak Krakatau. The flows have extended part of the shoreline by about 100 meters (330 feet). Tiny airborne liquid and solid particles (aerosols) emitted by the volcano likely helped form the clouds downwind of the summit.
The image was collected by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite on the morning of September 4, 2012. The Terra satellite captured an image of a larger ash plume erupted by Anak Krakatau on September 3.
