Bay of Bengal – Low Pressure – Update 28th November

The Low Pressure Area has now relocated as we had mentioned in our post today morning.  It now lies North East of Sri Lanka.  IMD expects this to intensify into a Well Marked Low (WML) over the next 24 hours or so.

Slide1

While conditions are moderately helpful for the system to intensify it still pretty much powerless against the High Pressure Area (HPA) over Central India which is moving down South as each day progresses.  Delta Regions have got decent rains today, with places upto Cuddalore & Pondy getting its share of moderate rains.  Because of the HPA the system has pretty much remained quasi stationery making little jumps to West and East.

Slide3

South Tamil Nadu, Delta regions have all got rains from this Bay disturbance,despite all expectations Chennai has not got any luck till now.

Slide4

For Chennai to get rains the system has to intensify a little bit and make a slight NW jump closer to Nagapattinam for meaninful rains to start.  Will that happen?  Models are expecting a SW movement after a quasi stationery position for a day or so.  We feel the system being in the open waters could intensify into a WML and possibly a Depression in the next 24 to 36 hours which could possibly bring Chennai under the northern bands of the system thereby providing some much needed rains.  As things stand we Chennaites have to bide our time and wait patiently for the rains.  The possibility of rains during the weekend as originally expected still stands at 50:50.  Lets hope for the best
