This week, a tyhpoon that is named Rammasun (this hurricane is known locally to residents of the Philippines as Glenda) passed over Manila Bay and just south of the core of Metro Manila through the morning in the Philippines. This typhoon then strengthened quite quickly on early Tuesday morning and remained a Category 3 equivalent storm for the most of the day. Higher terrain in the area has disrupted the circulation of Rammasun as it crossed the Calabarzon region and moved towards Manila. Thankfully for the residents, this led to some weakening of the system before the center moved into Manila and over the Manila Bay on Wednesday morning.
This typhoon’s winds are now estimated at about 90 miles per hour, which is down from its 125 mph peak, and now Rammasun is back over the open water about 130 miles northwest of Manila. This cell is now making its way through the South China Sea, and it is expected to regain most of its strength before it impacts China and then Vietnam late into the week, and even into the weekend. The main threat now is a potential for locally heavy rainfall and also the potential for dangerous landslides and this will continue over the next couple of hours over Luzon, but luckily the winds should begin to die down as the storm surge threat dissipates.
A hurricane expert with the Weather Channel has reported that a storm surge of up to 6-10 feet is expected along the coastal areas of eastern Visayas and central Luzon, along with a few wind gusts over 100 mph. This typhoon has caused about 4,000 ferry passengers and over 50 vessels to be stranded in ports along southern China thus far.
Rammasun will make its way into the South China Sea by Wednesday afternoon, where it is expected to strengthen signifcantly due to low wind shears and warm sea-surface temperatures. It is expected to make landfall in southern China near Hainan Island, which maintains a population of 8.9 million, on Friday evening. This typhoon may even reach a Category 3 equivalent by the time it makes landfall on the coastal areas of China.
In China, they have a four-tier warning system for typhoon. The China Meteorological Administration has now issued an orange warning for the provinces of Hainan, Guangdong, and Guangxi, which are all located in southern China. From there the storm will then make its way into Vietnam by Saturday. The system is expected to be the equivalent of a Category 1 or Category 2 typhoon by the time it reached Vietnam.
There are some storms over the western Atlantic that are associated with an upper level system, and the winds are definitely remaining unfavorable for any more development this week.
There was an area of low pressure that was present over the middle of the eastern Pacific that has slightly changed. Thankfully, the development of this system will stay over the ocean and isn’t a threat to land just yet.
