Aemet has activated a yellow alert for rain and hail in Castellón. The warning covers the northern interior, especially Els Ports, with up to 20 mm expected in one hour. Temperatures will vary across the region.
The State Meteorological Agency (Aemet) has issued a yellow alert for the province of Castellón, warning of heavy rain and thunderstorms that could bring hail, particularly in the Els Ports area. The alert is in effect from 14:00 to 22:00, targeting the northern interior where rainfall could reach up to 20 liters per square meter within a single hour. This measure comes after a brief period of stable weather in the region.
Forecast models from Aemet indicate that, while the most significant precipitation is expected in Els Ports, other areas such as Baix Maestrat, l'Alt Maestrat, and Alto Mijares may also see showers during the afternoon. However, rainfall in these zones is likely to be minimal compared to the northern interior. The alert highlights the risk of sudden downpours and localized hail, which could impact daily activities and local transport.
Across the wider Comunitat Valenciana, the start of September brings variable cloud cover and a low probability of light, scattered showers, especially in the southern half of the region. According to Aemet, these showers could be accompanied by mud due to dust in the atmosphere. Minimum temperatures are expected to rise or remain steady, while maximums may decrease or stay unchanged. In Alicante, temperatures are forecast to range from 22°C to 31°C; Castellón city will see similar minimums with highs up to 30°C; and in Valencia, the range will be 23°C to 29°C.
Weather warnings such as this are not uncommon in late summer, when atmospheric instability can trigger sudden storms. Local authorities typically advise residents to stay informed and take precautions during alert periods. The impact of severe weather has been felt in other parts of Spain as well, as seen when storms in Tarragona led to tragic incidents, including a fatal wall collapse in Roda de Berà that prompted official mourning.
For residents and visitors in Castellón, the current alert underscores the importance of monitoring official updates and being prepared for rapid changes in weather conditions. The yellow alert system is designed to warn the public of potential hazards without causing unnecessary alarm, allowing people to adjust their plans and minimize risk. As the region enters September, such advisories serve as a reminder of the unpredictable nature of Mediterranean weather patterns and the need for ongoing vigilance during storm-prone periods.
