Stations across Thailand and Malaysia are reporting rainfall amounts of anywhere from 50 to as much as 150mm causing flooding in many areas. 91W is not forecast to develop into a cyclone anytime soon. However, it is expected to continue bringing widespread rains across Indochina over the next 48 hours with the possibility of additional 50 to even 100mm of rain. 91W may develop once it reaches the Indian Ocean.

Meanwhile, the ITCZ continues to flare up near the tropics. Rain showers may affect parts of Micronesia and even Mindanao in the Philippines in the coming days. Luzon and Visayas, on the other hand, will continue to have warm weather with occasional thunderstorms in the afternoon and early evening hours.
