Due to the impact of Typhoon Danas, categorized as the fourth typhoon, the National Marine Environmental Forecasting Center has issued a blue warning for potential storm surges. Predictions indicate that a storm surge of 30 to 70 centimeters could hit the coastline stretching from Ningde, Fujian, to Ningbo, Zhejiang. However, the expected tide levels will not reach the threshold for a blue warning. Nonetheless, relevant departments should be prepared for defensive measures, and maritime units should take appropriate steps to ensure safety.
