Where exactly it Rains Heavily in Andhra??

Andhra Pradesh gets Rainfall from Two Monsoons....Firstly the Summer Monsoon(June-September) and the Retreating Monsoon(October-December). During The period of Summer Monsoon, the rainfall will be associated with the Low pressure Monsoon systems forming over Mid-Central Bay of Bengal close to Odisha and North-Andhra coasts. The Monsoon low pressure systems dump flooding rains and causes floods over Krishna and Godavari systems. Sometimes, the local troughs contribute to heavy rainfall. Heavy monsoon corresponds to more and more rainfall...

Districts which receives South-West Monsoon Rainfall-

The districts like-

1)Vizianagaram

2)Visakhapatnam

3)Srikakulam

4)Guntur

5)Krishna

6)East-Godavari

7)West Godavari

8)Parts of Prakasham district

9)Kurnool district

10)Anathapuram district

11)Kadapa district

These above districts depend on Summer Monsoon rains and accounts to 60-80% of Annual Rainfall. While the districts like Nellore, Chittoor Districts gets very less Summer Monsoonal rainfall (less than 40% of annual rainfall).

During Summer Monsoon, the heavy rainfall is confined to North coastal districts of Andhra and the South Andhra districts gets less rainfall. Anathapur, Kadapa, Kurnool, Western parts of Chittoor district gets less rainfall.

"North-East Monsoon Role in Making up Rainfall"-

During the Months of October and November, the Monsoon retreats fast and the cyclonic systems develop over South parts of Bay of Bengal. They generally move in North-West Directions and Affect North Tamilnadu-South Andhra Coast. Places like Tirupati, Nellore, Srikalahasthi, Kavali gets heavy to Very heavy rainfall. Some times floods are often over these places during this time. The places like Tirumala gets Extremely heavy rainfall due to Orographic lifting of clouds.

The above Picture Tells a very active North-east Trade wind flow over South Andhra and Tamilnadu coast, resulting in a heavy rainfall.

So which City can be crowned as Andhra's Rainfall King??-

So, to solve this riddle, I took the data of Andhra's rainfall and tried to bring out 5 places, which stand top spots in the competition. The places are-

1)Tirumala

2)Araku

3)Srikalahasthi

4)Tirupati

5)Amalapuram

-- Out of these places, the places like Araku and Amalapuram gets heavy rainfall during Summer Monsoon and the remaining places Tirumala, Tirupati, Srikalahasthi gets heavy rainfall due to Cyclonic systems crossing Bay of Bengal. The places of Coastal will get unless the Bands organize well over the system. Where as, the places provided with Hill-lock systems gets torrential pounding by blocking and raising the clouds. So we can rule out the places like Tirupathi, Srikalahasthi, Amalapuram.

Taking Tirumala and Araku into consideration, we reach a tie breaker....Tirumala average tends to 1477.5mm and araku gets 1098.7mm...But when compared to Tirumala Annual rainfall, the araku rainfall is less. But araku consistently reaching its average inspite of Floods/Drought prevailing over the region of Visakhapatnam district. Hence, i prefer Araku and the surrounding areas are the places in Andhra, where the Heaviest rainfall is concentrated. Whatever it may be, cyclonic or Convectional, rainfall will hit these places, which is not the case in Tirumala. But the place of Tirumala gets extremely heavy rainfall (greater than 25cms) if any Cyclone hits the coast of South-Andhra pradesh.

At the same time the cyclone will pull away the moisture over Andhra and Tamilnadu....letting the intense heat over Gujarath and Maharastra to dip south. There will be a drastic increase in heat over Andhra by 23rd. Many places over Andhra, North-interior Karnataka and Telangana will get 44-46 degrees back.

FORECASTED RAINFALL-

MONSOON ONSET AND PROGRESS??

The much awaiting South-West Monsoon likely to make its progress soon after the landfall of "Cyclone Roanu". Rains will start in Kerala by June 3rd and take a sharp progress thereafter. Cyclones in bay of Bengal make Monsoon onset late, by making the Bay of Bengal Branch Much stronger. According to GFS, the monsoon is likely to touch Kerala shores by june 2nd.

LATEST MONSOON STATUS-

IMD(Indian Meterological Department) issued a heavy rainfall warning to Nicobar islands on the event of Monsoon onsetting. Heavy rain likely to continue over Nicobar islands for next 3 days..then it will shift to Andaman islands.

Cyclone-Roanu Performance Over Andhra Pradesh-

The cyclonic storm Roanu, which moved close to Andhra Pradesh, Triggered a heavy dumping deluge with highest touching 35cms of rainfall over Sricity and 24 cms over Tada. Advance to say, It triggered over 29cms over Amalapuram and Avanigadda got 17cms. Tirupathi, which is 76kms away from coast, got 16.1cms overall from this system. Vishakapatnam received a staggering rainfall of 22cms.

ROANU DATA-

Note-

Also, it is said that the Deep-Sea areas got a bulk rainfall ranging from 650-800mm's with coastal areas getting less than 35cms. Interior areas got negligible rainfall, with Tirupathi being an exceptional case. Madanapalle, Hyderabad, Bangalore got some Isolated Thundershowers, which resulted in a relief from burning heat. Still there is a deficit in interior areas. Pre-Monsoonal Rainfall will resume after 28th May over interiors, with a good rain showers to Bangalore. These showers are temporally being halted by Cyclone Roanu.
