Weather forecast for Kuala Lumpur produced at 9:45 AM Monday March 20

Kuala Lumpur 7 day weather forecast produced at 9:45 AM Monday March 20:
Explanatory notes:

Update:The forecast has been updated to reflect the rain over the area this morning caused by a mesoscale convective system which formed over the Straits of Melaka overnight with the aid of land breeze convergence.

Today(Monday March 20) the region lies within the doldrums but a steering flow somewhat from the west is expected.

Then during Tuesday and Wednesday northwesterly low level winds are expected over the region and a steering flow somewhat from the west as well as the southern monsoon trough south of Indonesia strengthens along with the possible development of a tropical cyclone south of Java island within that monsoon trough.The Perth Tropical Cyclone Warning Center(TCWC) of the Australian Bureau of Meteorology(BOM) expects a medium chance(20-50% chance) of a tropical cyclone developing within that region on Wednesday increasing to a high chances towards the end of the week but then this potential tropical cyclone will be very far from the forecast area and thus the effect from this system on the weather patterns over the forecast region will be reduced towards the end of the week .

Medium to high chances of showers and thunderstorms are still expected then(during Tuesday and Wednesday) with the atmosphere remaining moist and unstable and the steering flow then also means a slight chance of showers and thunderstorms in the morning, mainly over coastal areas as showers and thunderstorms which form offshore due to land breeze convergence are steered towards the coast.

Then from Thursday the doldrums lie over the region again with light low level winds,this should also lead to a high to very high chances of showers and thunderstorms especially in the afternoon/evening but there is some uncertainty with possible dry air moving in aloft then.
