Danas is characterized by wide-range influence in terms of wind and rain, a large amount of rainfall during the weather process, and a long duration on land.

Meteorological departments of Zhejiang and Fujian have taken preemptive measures to build the first line of defense to guard against the impacts of Danas, and reinforced joint coordination with other departments to tackle Danas in a comprehensive manner. They also fully leveraged early warnings to better tackle the impacts of Danas.

On the night of July 8, Typhoon Danas made landfall successively in Dongtou, Wenzhou and Rui'an, bringing wind and rain to many areas in Zhejiang.

Meteorological departments of Zhejiang promptly reported the movement and the impacts of wind and rain to the provincial government, and teamed up with provincial departments such as emergency management, water conservancy, natural resources, culture and tourism, transportation, and agriculture and rural affairs to enhance monitoring, forecasting and early warning services.

In response to the upcoming typhoon on July 5, Zhejiang Provincial Meteorological Observatory (hereinafter referred to as the Observatory) and provincial fishery emergency response command center jointly issued the "Marine Fishery Meteorological Risk Warning". This is also the first time that Zhejiang Provincial Meteorological Service and the provincial Department of Marine Economic Development  jointly issued a warning to cope with the impacts of Danas.

The Observatory also harnessed its independently developed typhoon report form production system to produce and release the "Typhoon Report Form" along with its track and related products of wind and rain with one click within 15 minutes, and has guided meteorological departments of cities to issue forecasts and warnings.

Guided by meteorological warnings, all coastal marine engineering projects in Wenzhou, Taizhou, and Ningbo were suspended, and all operating vessels returned to ports for shelter. With peak island tourism season underway, Pingyang County Meteorological Office in Wenzhou issued an offshore gale forecast, county-wide refined risk warnings, and decision-making recommendations on July 5. Besides, on July 6, Nanji Town government, Wenzhou Aojiang Maritime Safety Administration, and Pingyang Communications Investment Group (CIG) Port Company activated contingency plans, organizing safe and orderly evacuation of 1,304 tourists from scenic areas including Nanji Island. All ferry services to Nanji were suspended the following day.

Besides, in the aftermath of the landfall of Typhoon Danas, it has stagnated with the region of Fujian for over 20 hours, incurring grave windy and rainy weather. Meteorological departments of Fujian deliver progressive meteorological services, and lay a foundation for the typhoon prevention and flood control work.

Fujian Provincial Meteorological Service promptly activated the "1262" meteorological flood prevention linkage mechanism and delivered progressive meteorological services. It jointly issued risk warning products with the Provincial Department of Natural Resources and Provincial Department of Water Resources.

Confronted with complex and volatile typhoon cloud systems, Fujian Provincial Meteorological Observatory has continuously upgraded its OTS Algorithm, integrating minute-scale precipitation and extreme wind data to enhance short-range forecasting capabilities for intense rainfall and thunderstorm gales. Within the intelligent grid forecasting platform, a typhoon wind radius impact function has been developed and integrated, delivering more precise information on the scope and intensity of typhoon-induced gale.

On July 8, meteorological observatories across 5 cities (districts, counties) in Fujian issued targeted early warnings through the Emergency Warning Information Release System.

In face of the 4th typhoon of this year, meteorological departments of affected regions have taken active preventive measures, and conducted progressive meteorological services  to ensure the safety of the people and the smooth operation of the economic and social development.
