The warning, which remains in effect throughout the day, highlights the potential for intense weather activity that could disrupt daily routines.
According to the latest reports from the SMN, the region is expected to experience storms of varying intensity, with some areas facing locally strong or severe conditions. Meteorological forecasts indicate that these storms may bring significant rainfall in short periods, along with the possibility of hail, frequent electrical activity, and wind gusts that could reach up to 90 kilometers per hour.
There is some variation in the projected precipitation totals among meteorological reports. While some initial estimates suggested lower accumulation, updated warnings from the SMN suggest that total rainfall could range between 30 and 90 millimeters, with the possibility of exceeding these values in specific locations. These conditions have prompted authorities to urge residents to remain vigilant.
The temperature in Formosa is expected to reach a high of 33 degrees Celsius, with a minimum of 23 degrees Celsius. Humidity levels are anticipated to remain high, fluctuating throughout the day. These atmospheric conditions are consistent with the typical patterns monitored by the national agency, which utilizes a network of meteorological stations, satellite imagery, and numerical prediction models to track such events.
The SMN defines a yellow alert as a situation where meteorological phenomena have the capacity to cause damage and pose a risk to the temporary interruption of daily activities. The agency emphasizes that these warnings are issued to support decision-making for various sectors, including aviation, agriculture, and general public safety, often providing notice 24 to 72 hours in advance of an event.
Looking ahead, the weather in Formosa is expected to remain unsettled. The forecast for November 5 indicates continued light rain with temperatures ranging between 20 and 31 degrees Celsius. As the week progresses, the region will likely see a mix of cloudy skies and further light precipitation, with temperatures cooling slightly toward the end of the week, oscillating between 18 and 27 degrees Celsius by November 8 and 9.
Authorities remind the public that a yellow alert is a precautionary measure intended to protect the population. Residents are encouraged to stay informed through official channels and to take necessary actions to secure their property and ensure personal safety during the duration of the storm warning.
