Wow GSB...what a herculean task and effort.
Vagaries really proud to have you as co author.
Appreciate the tenacity to get the data available in this format. TKes huge focus and discipline. Kudos
Great effort GSB Sir!! This list gives good insights about the regional 'wet spots' in different states.
Thanks Rajesh sir. With your blessings hope to make many more such reports in the future.
Thanks Shreyas. The North East and some pockets in the south and west of the country are bright spots as far as annual rains are concerned. I'll try and make a graphical representation of these numbers for more clarity.
With brilliant minds like you in our group encouraging us all the way,nothing is impossible.

La Niña expected to ease over summer
La Niña continues in the tropical Pacific but is slowly weakening. However, while ocean temperatures have warmed in recent weeks, atmospheric indicators remain at La Niña levels. La Niña typically increases the chance of above-average rainfall for northern and eastern Australia during summer.
Long-range forecasts suggest that tropical Pacific Ocean temperatures will continue to warm towards El Niño–Southern Oscillation neutral levels over the coming weeks. Some change in atmospheric patterns towards neutral levels is also possible. As long-range forecast accuracy is generally lower at this time of year, ENSO outlooks that extend through autumn should be viewed with caution.
The Southern Annular Mode (SAM) is strongly positive and is likely to be positive until at least mid-January. During summer, a positive SAM increases the chance of above-average rainfall for eastern New South Wales, eastern Victoria and north-east Tasmania. It increases the chances of below-average rainfall for western Tasmania.
The Madden–Julian Oscillation has been in the western Pacific since late December and is forecast to move into the Atlantic in the coming days. This may cause an easing in trade wind strength and increase cloudiness near the dateline. This could potentially weaken some indicators of La Niña.
Sea surface temperatures remain warmer than average in the western Pacific, much of the Maritime Continent, and around northern Australia. Warmer Australian waters, especially in the tropics, can result in greater evaporation, humidity, cloudiness, and rainfall.
