A low-pressure area that formed on Sunday over the Southwest Bay of Bengal continues to move westward and fuels moisture that keeps the northeast monsoon active. The IMD says another low-pressure area may develop over the Southeast Bay of Bengal around November 22 and may intensify in the coming days.
