Typhoon Domeng intesifies, threatens Philippines which may bring heavy rains to Visayas and Mindanao
Tropical depressions #90W (#DomengPH) and #91W have changed little in organization as they remain nearly stationary in the Philippine Sea well to the north of Palau. 91W's circulation has become ill-defined, and satellite imagery suggests the two systems have begun to interact with one another. Further development of the two systems is not anticipated during the next 24 hours or so as they remain in the same general area. JTWC has canceled the TCFA they had previously issued for 91W.
After the next 24 hours, however, 90W and 91W should merge into a single, larger disturbance. Conditions will be conducive for development of that system as they move slowly to the north and remain east of the Philippines during the next few days, and it could become a tropical storm before the subtropical westerlies force it to race off to the northeast by the end of the week. Although this system is not expected to be a direct threat to any land areas, southwesterly inflow into the system could cause some scattered showers and thunderstorms over parts of Samar and the Visayas during the next few days.
