The Central Weather Administration of Taiwan has again issued a “Sea and Land” typhoon warning for all regions of Taiwan. The National Meteorological Center, China, also issued a Red typhoon warning to Fujian. As for damaging winds and precipitation orders, please stay indoors, follow the CWA instructions, and prepare for arrival if you’re in Fujian. If you live in one of the regions affected by Gaemi’s path as of damaging winds and precipitation in order, please stay indoors, follow the instructions of CWA, and prepare for the arrival if you’re in Fujian.

Current Forecast

Gaemi will continue weakening as it traverses through Taiwan and will land over Fujian again tomorrow evening, still as a broad system. It is expected to go further inland and dissipate over the weekend, yet its remnants, coupled with the monsoon, will still bring precipitation to the Philippines, Central, and Southern China.

Current Hazards

Typhoon Gaemi is now bringing heavy rainfall and strong winds to most areas of Taiwan. Rainfall measures more than 130 millimeters and gusts up to 55 meters per second are in the middle regions of the Taiwanese island and Penghu County.

Current Information

Recently, Gaemi was located at 23.5 degrees north, 123.3 degrees east, and was moving northwest at 7 miles per hour. The current intensity from JTWC is estimated to be 120kt, with a minimum central pressure of 0f 935mb. However, recent radar velocity data from early morning in Ishigaki suggested a higher intensity, as high as 140-145kt, as 01:05Z data showed a 165kt 4-binned velocity at around 2km height.

Current Warnings and Watches

The Central Weather Administration of Taiwan has issued a “Sea and Land” typhoon warning for almost all regions except Kinmen County. Additionally, the JMA has issued emergency storm surge warnings for the areas of Yaeyama and Miyakojima. In the Philippines, the PAGASA has issued red rainfall warnings for Metro Manila, Bulacan, Pampanga, Rizal, Bataan, and Zambales, as continuous rainfall has led to massive rainfall amounts. If you live in one of the regions affected by Gaemi’s path, please monitor additional warnings or watches issued by your national meteorological service in your area.

Current Forecast

From the cone forecast issued by the JTWC, Gaemi will curve and make landfall on the island of Taiwan by July 24th at approximately 12Z, then move into the mainland of China on July 25th at 12Z.

Current Hazards

Typhoon Gaemi is expected to bring heavy rainfall and strong winds to most areas of Taiwan, with rainfall measuring more than 130 millimeters and gusts up to 55 meters per second in the middle regions of the Taiwanese island, making outside preparations difficult or dangerous. Additionally, storm surges generated by Gaemi are expected to reach the Japanese areas of Yaeyama and Miyakojima, measuring up to 2.1 inches. Preparations should be rushed as Gaemi is likely to arrive in Taiwan tomorrow. 

In the Philippines, rainfall is the biggest story, as the storm has enhanced the southwest monsoon season. The Marikina River has risen to 18m (59ft) at 2 am UTC, forcing the 3rd alarm to be issued. The Science Garden in Quezon City has logged more than 200mm (8 in) of rainfall in 24 hours, while the Tanay automated weather station in Rizal had a new record of 261.6mm (10.3 in) in 24 hours, surpassing its record in 2000. Evacuate when directed by officials, and stay tuned to your local weather service for further updates.

Current Information

As of 18Z on July 21, 2024, Gaemi was located 17.6 degrees north, 129.9 degrees west, and was moving north-northeast at four mph. The

latest outlook on tropical storm Gaemi’s stats by the JTWC analyzed maximum winds of around 58 mph and a minimum central pressure of 991 millibars.

Current Warnings and Watches

The Central Weather Administration has not issued warnings or watches in Taiwan. Still, in the Philippines, PAGASA issued a Tropical Cyclone Wind Signal One, meaning that the island of Luzon will be little impacted. If PAGASA issued you a Tropical Cyclone Wind Signal One, please monitor additional advisories and inspect whether your house needs repair or reinforcements from the storm system.

Current Forecast

According to the cone forecast issued by the JTWC, Gaemi will curve and then make landfall in Taiwan by July 25th at midnight UTC, then move inwards to Fuzhou later on July 26th at midnight UTC.

Current Hazards

Tropical storm Gaemi will soon spread strong winds to the areas of Taiwan and Fuzhou and is expected to bring heavy rainfall there, making outside preparations difficult. Meanwhile, storm surges are expected to reach the Japanese islands of Ishigaki, Taketomi, Tarama, and Yonaguni, as well as the island of Taiwan, making them potentially life-threatening to those islands mentioned. Preparations should be completed by the time Gaemi lands in Taiwan by July 25th, 2024. Evacuate when directed by your officials, and stay tuned for updates about Gaemi’s status from your local weather agency.

The storm is expected to brush past the coast of southern Guangdong, Hong Kong, and Macau over the next 24 hours, bringing storm surge, strong winds and heavy rainfall, and up to 300mm of rain could fall in the region, causing flash flooding and landslides.

Typhoon Haikui is also intensifying as it limbers towards Taiwan, where it is expected to strike this weekend, where the storm is expected to drop huge amounts of rain over the island and on to eastern China, where rain totals could accumulate to over 500mm.

The storm is expected to make landfall as a Category 1 or 2 typhoon.

Ex-hurricane Idalia is now an extratropical cyclone and is approaching Bermuda, where it is expected to regenerate into a tropical storm, and watches are now in effect for the island.

The storm is expected to once again turn post-tropical by Tuesday.

In the West Pacific, Tropical Storm Kirogi is struggling, while a hemisphere away tiny Tropical Storm Jose is expected to remain short lived under the shadow of Hurricane Franklin, which itself is on its way out.

Further systems are expected to develop in the Atlantic and Eastern Pacific, with trouble brewing in the Western Pacific again next week.

The post Typhoons Impacting China, Taiwan and Hong Kong – Tropical Weather Bulletin – September 1, 2023 appeared first on Force Thirteen.

Yutu has moved south of what was forecast at the time of the publishing of my last article, and is almost certain to make a landfall on the Philippines rather than cross just north of the archipelago nation. The Filipino government has already issued signal one warnings for large portions of the northern region of Luzon, and heightened warnings are very likely to be issued in the coming day.

The typhoon is expected to cross over the largest Philippine island in less than one day, bringing life threatening rain, winds and storm surge. Unfortunately, the same region that is being impacted by Yutu in the coming day is the same area that was devastated last month by Super Typhoon Mangkhut, which made landfall in Luzon as a category 5 storm.

To protect its people from potential harm in another natural disaster, the Filipino government is already taking action. In Cagayan, governer Manuel Mamba led a pre-disaster risk assessment where he told officials to evacuate residents in prone locations by the end of Monday, October 29th. He also suspended classes of all levels for the whole province on Monday and order disaster response teams to prepare to respond to the storm. Preparations like the ones in Cagayan are being issued across all of the Northern Philippines as gale force winds and heavy rain are expected to spread several hundred kilometers away from the center of the storm.

Elsewhere, Southern China and Taiwan are closely monitoring the progress of Typhoon Yutu as it may impact either area after it passes through Central Luzon. The current forecasts from the Joint Typhoon Warning Center and PAGASA both call for the storm to cross into the South China Sea, but where the system may track after reaching this area is uncertain. Some models take the storm as far west as Hainan Island while others take the storm just offshore of western Taiwan.

Regardless, Yutu remains an extreme threat for a region that already been impacted by Super Typhoon Mangkhut, and may not be fully recovered from its effects. The government is acting to protect its people, but the time for preparations is running out as the dangerous storm bears down on the island nation.

Authors Note: To anyone reading this article that lives in the Philippines, Southern China, or Taiwan, please listen to local officials for any information. This is a potentially deadly situation, and it is key that you follow orders given by officials for your safety.
