  1. Some news on this cyclone currently developing
    ” The deep depression is likely to move North over the next 48 hours, intensifying simultaneously, and then move in the Northeastern direction, away from the coast.

    From the ASIAN AGE

    This follows the recent cyclone LEHAR I the bay of Bengal recently.
    The outlook from this report indicates

    ‘It is currently stationed 266-km Southeast of Chennai. Rainfall has been predicted along coastal Tamil Nadu while Southern Andhra coast is also likely to witness showers over the next 48 hours’.

    Cyclone MADI —DECEMBER 10TH 2013

    The long-term future of Tropical Cyclone 06B is not certain at this time. Two scenarios exist: the first causing the storm to stall east of India early next week then reverse course and track south or southwest toward southeast India and Sri Lanka later next week.!!

    Parts of eastern Sri Lanka received 150-300 mm (6-12 inches) of rainfall last week

    and could have another round of rainfall later this week as Madi returns from the north.

    Madi is expected to be nearly stationary into Tuesday before turning southwest and eventually approaching southeast India and northern Sri Lanka later this week.

    This track will bring another round of tropical downpours to southeast India, mainly from Chennai southward and also across the northern third of Sri Lanka.

    The positive news is that Madi will weaken as it brings this second round of downpours to India and Sri Lanka, so no widespread flooding is expected. However, localized amounts in excess of 100 mm (4 inches) will be possible and could lead to flooding problems.

    Although the center of Madi will track to the southwest this week, much of the moisture will be pulled northeastward by strong wind shear.

    This will bring rounds of moderate to heavy rainfall to Myanmar which could cause some flooding problems.

    The moisture will then continue to stream northeast, interacting with a frontal boundary over southeast China where a more widespread threat for flooding will be possible by this weekend

    Tropical Cyclone Madi is headed for a landfall in southeastern India

    Forecasters at the Joint Typhoon Warning Center or JTWC now expect Madi to turn to the southwest and make landfall in southern India in Tamil Nadir on December 12.

    ..
    ..The current track for the center of the cyclone brings it between the coastal city of Puducherry and the town of Mannarguddi, both along the southeastern coast. Forecasters will be closely watching Madi as it moves across India as some forecast computer models suggest that its remnants could re-emerge into the Arabian Sea.
