1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 2.8N 87.7E,
APPROXIMATELY 530 NM EAST-SOUTHEAST OF COLUMBO, SRI LANKA. ANIMATED
MULTISPECTRAL IMAGERY AND A 071228Z QUIKSCAT IMAGE SHOWS A BROAD
REGION OF TURNING WITH POSSIBLY MULTIPLE LOW LEVEL CIRCULATIONS
CENTERS (LLCC) EVIDENT. RECENT INCREASES IN CONVECTION ALONG THE
PERIPHERY OF THE REGION ARE BEGINNING TO SHOW SIGNS OF WRAPPING
TOWARD THE LLCC. UPPER LEVEL ANALYSIS INDICATES THE REGION IS UNDER
THE INFLUENCE OF MODERATE TO HIGH VERTICAL WIND SHEAR BUT HAS GOOD
POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES IN THE AREA ARE FAVORABLE
FOR DEVELOPMENT AS WELL. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1005 MB. BASED ON POOR ORGANIZATION OF THE LLCC AND
MODERATE TO HIGH VERTICAL WIND SHEAR, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS POOR.

Its a bit early for anything significant to develop in this part of the Ocean.

CONVECTIVE CLOUDS ARE SEEN OVER PARTS OF SOUTH bay of bengal and south ANDAMAN SEA.

Nothing new with this disturbance,still poor for any development:

Tropical Cyclone Outlook (1800z 08Mar)
====================================
Under the influence of the trough of low at Sri Lanka over southwest Bay of Bengal and N/H

A low pressure area has formed over the same area associated circulation up to 2.1 kms ASL


---
I have no idea what N/H means so I didn't bother trying to convert it like I did for SL meaning Sri Lanka.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.7N 83.9E,
IS NOW LOCATED NEAR 6.5N 82.0E, APPROXIMATELY 130 NM EAST OF
COLOMBO, SRI LANKA. ANIMATED ENHANCED WATER VAPOR IMAGERY SHOWS AND
A 082007Z AMSR-E MICROWAVE IMAGE DEPICTS DEEP CONVECTION DEVELOPING
OVER A BROAD REGION OF TURNING CONSOLIDATING INTO A LOW LEVEL
CIRCULATIONS CENTER (LLCC). UPPER LEVEL ANALYSIS INDICATES THE
REGION IS UNDER THE INFLUENCE OF LOW TO MODERATE VERTICAL WIND SHEAR
AND HAS GOOD POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES IN THE AREA
ARE FAVORABLE FOR DEVELOPMENT AS WELL. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
FAIR.

You never know....it might just reappear across the Southern tip of India in Arabian Sea.

Chief Meteorologist Forecast (0900z 09Mar)
====================================
Morning’s low pressure area over southwest Bay of Bengal & adjoining Sri Lanka persists.

The system may become well marked during next 24 hours. Under its influence, scattered to fairly widespread rain/thundershowers are likely over southern peninsular India during next 48 days.

High Sea Forecast Bulletin (1800z 09MAR)
=====================================
The low pressure area over southwest Bay of Bengal and adjoining Sri Lanka persists.

Associated cirulation now extends up t0 2.1 km ASL. System is likely to become more marked.
