This year, Northeast Monsoon has performed average over the entire state of Andhra Pradesh. As a result, the state has remained largely rain deficient by 66%.
However, southern districts of Andhra Pradesh such as Nellore and Chittoor have performed comparatively well with moderate to heavy showers recorded over these places. The reason for these rains can be attributed to the formation of significant systems such as Cyclone Gaja as well as low pressure areas over the southern parts of Bay of Bengal.
At present, residents of Andhra Pradesh are battling dry weather conditions in the absence of any significant rains. However, rains are once again making their way to the coastal state.
A low pressure area has formed over South Central Bay of Bengal and is likely to gradually intensify into a depression in the next 24 hours. The system would move in west- northwest direction towards South Andhra Pradesh as well as North Tamil Nadu. This intensified system is then expected to reach near the coast around December 14. Hence, we expect heavy to very heavy rains over many districts of the state such as Nellore, Prakasam and Chittoor December 15 onward.
Moreover, this system would also affect the remaining districts of the state in the form of light to moderate rains.
However, as this weather system moves further in northwest directions towards Telangana, most probably around December 16, rain intensity will reduce significantly. Thus, only scattered rains are likely on December 17, while isolated showers are expected on December 18 over most the districts of the state. However, intensity of these rains will continue to be high over South Andhra Pradesh.
Talking about temperatures, due to the humid winds approaching from Bay of Bengal, minimums will now increase. On the other hand, day temperatures will fall. Further, we expect a significant decrease in day temperatures around December 15 and 16 because of clouding.
