March 1st 2nd week rains

Just two days away from rains.....March 1st to 10th
MJO moving into our basin (Indian ocean) is one of the reason for Rainfall over entire TamilNadu during 1st two weeks of march.

The trough in low level easterlies over equatorial Indian Ocean &
adjoining southeast Bay of Bengal extending upto 0.9 km above mean sea level persists. (IMAGE 1)
As this low will move through Gulf of Mannar or Comorin Sea (Kanyakumari) south TN will see Rain Blast.

Rains will start from March 1st evening or from early March 2nd over South Tip and SE of TamilNadu places likely Nagercoil, Tirunelveli. From 3rd gradually south interior and delta will see rains, Western TamilNadu like Nilgiris(Moisture Trapper), Coimbatore, Tirupur, Pollachi has good chances witness some good spells.(Moderate to Heavy)

North coastal region from cuddalore to chennai and N interior like Dharmapuri, vellore, salem will witness light to moderate showers not much expected as of now. Heavy spells stays in south TamilNadu. Its going to be relief from heat for next 2 weeks.
