Meteorology expert "Taiwan Typhoon Forum | Weather Emergency" stated that there are still three typhoons coexisting in the northwest Pacific. Typhoon Caiyun is significantly larger in size. It is currently located off the southeastern coast of Japan. The intensity is a moderate typhoon. It will turn to the northeast and accelerate and gradually transform into an extratropical cyclone. The weather in the Shuangbei region has stabilized, with only the northern coast of Keelung and Yilan experiencing brief light rain.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science of National Central University, pointed out that due to the influence of the northeast monsoon, the rain in northern Taiwan has gradually stopped today and the water vapor has moved southward. From tomorrow to Friday morning, the temperature will be low. The lowest temperature on the plains can drop to 16 degrees, and the temperature difference between day and night is large; the three typhoons (Caiyun, Noro, and Xiaoxiong) have not posed a threat to Taiwan.

China Weather Network reported that due to the continuous rainfall, Hainan will experience widespread rainfall in the next three days (October 6 to 8). The scope of heavy rainfall will gradually expand, and local areas will experience heavy rainstorms or extremely heavy rainstorms. The meteorological department reminds the public to pay attention to travel risks such as slippery roads and reduced visibility, and to plan their itinerary appropriately during the peak return period during the National Day holiday.

Affected by the northeast monsoon, northern Taiwan will be cloudy with local brief showers. Tonight to tomorrow morning will be the lowest temperature period. The low temperature in the area north of Hsinchu is forecast to be 16 to 19 degrees; the three offshore stations (Caiyun, Noro, and Little Bear) are not expected to have an impact on Taiwan. The impact of Typhoon Little Bear on Japan is still variable and requires continuous observation.

The meteorological expert "Taiwan Typhoon Forum - Weather Emergency" released a 48-hour precipitation forecast, pointing out that due to the influence of the northeast monsoon on the 6th, the water vapor will decrease significantly, and the weather in both north and south will gradually stabilize. Only the north coast of Keelung and Yilan will have a chance of short-term light rain, and the rest of the areas will remain sunny.
