Four typhoons to form in the Southern Ocean; if they form, they will be Typhoon No. 25; first time in seven years that four typhoons have formed


2024/11/11 07:00

TOPICS IMG

By the evening of the 11th (Monday), a tropical depression near the Mariana Islands is expected to develop into a new typhoon as it moves westward. If it does become a typhoon, it will be the fourth this month and will be called Typhoon No. 25.

We have already seen triple typhoons, with Typhoon No. 22 in the South China Sea, Typhoon No. 23 east of the Philippines, and Typhoon No. 24 off the coast of Minamitorishima, but if a new typhoon forms, it will be the first time in seven years since July 23, 2017 that there will be four.

The new typhoon is also expected to move westward in the future, so it is expected that the Philippines will be greatly affected. At this point, there is no indication that there will be any impact on the Japanese archipelago, but in the past, typhoons have made landfall on Honshu at the end of November, so we must not let our guard down yet.

Today, Monday the 11th, the start of the week, rain will fall mainly in the morning in Hokkaido and the Pacific side of eastern and western Japan. In the afternoon, the front and low pressure will move away, and the weather is expected to improve.

The expected maximum temperature will be over 20 C from southern Tohoku to Kyushu. Some places, such as Nagoya and Kochi, are likely to experience summer days.

In Okinawa and Amami, the peak of heavy rain has passed, and the sunshine is expected to return today.








Okinawa and Amami: Continue to be on high alert for landslides; atmospheric conditions are extremely unstable through tomorrow


2024/11/10 17:50

TOPICS IMG

There is a low pressure system in the East China Sea, which is expected to move south of Japan tomorrow, the 11th (Mon).

Warm and humid air will flow toward the low pressure system, so the atmospheric conditions in Okinawa and Amami will continue to be very unstable until tomorrow, the 11th (Mon).

Due to the record-breaking rainfall so far, there are areas where the ground has become loose and rivers have risen in water, so even a small amount of rain may increase the risk of landslides, flooding, and flooding.

*Rain forecast

Today, the 10th (Sun), there will be heavy rain with thunder in some areas in Okinawa and Amami.

Today's predicted 1-hour precipitation
Amami: 40mm
Okinawa: 30mm

Predicted 24-hour precipitation until tomorrow evening
Amami: 60mm
Okinawa: 50mm

Today, the 10th (Sunday), in Okinawa and Amami, please be on high alert for landslides, and be on guard against flooding in low-lying areas and rising and overflowing rivers.

Also, be on guard against lightning strikes, tornadoes, and other violent gusts of wind.

If there are signs of an approaching developed cumulonimbus cloud, please take steps to ensure your safety, such as moving inside a building.

The moon and Saturn are approaching! Fomalhaut in Piscis Austrinus is also in the forecast for tonight


2024/11/10 13:20

TOPICS IMG

Tonight and tomorrow, the 11th (Monday), the young moon will be approaching the southern evening sky, and Saturn, shining at a brightness of 0.8 magnitude.

Tonight the moon is to the west of Saturn, but tomorrow night it will move to the east, so let's take a look at how much the moon's position changes overnight.

Below Saturn, Fomalhaut in Piscis Austrinus, the only 1st magnitude star in the autumn constellations, also shines.

These stars stand out well among the many faint stars around them, making them easy to observe.

Why not take a look at the southern sky tonight

Unfortunately, clouds are likely to spread around Japan tonight on the 10th (Sunday), and rain is expected on the Pacific side of eastern Japan, Shikoku, and Kyushu.

Hokkaido will also have a lot of clouds, but there will be sunny spots on the Pacific side.

On the other hand, northern Tohoku will be completely clear, making it possible to enjoy stargazing.

In the Nansei Islands, rainy weather will continue on Okinawa Island and Amami, but the Sakishima Islands will be sunny.

Tonight, temperatures will be lower than during the day in western Japan, the Sea of Japan side of eastern Japan, and northern Japan.

Please dress warmly when observing the stars outdoors.








[Typhoon forecast] If typhoons occur, there will be four in November. Pay attention to their future paths.


2024/11/10 11:30

TOPICS IMG

Currently, three typhoons, Typhoons 22, 23, and 24, have formed.

In addition to these typhoons, the Japan Meteorological Agency has announced that a tropical depression in the Caroline Islands is expected to develop into a typhoon within 24 hours.

The next typhoon to form will be called "Typhoon 25."

According to the latest forecast, this tropical depression will continue to develop after becoming a typhoon and move east of the Philippines, and is expected to become a storm area by 9:00 on the 13th.

The course beyond 9:00 on the 15th has not been determined.
Please pay attention to future developments.

Typhoons No. 23 and No. 24 occur in succession; triple typhoon in November


2024/11/09 23:33

TOPICS IMG

At around 3:00 p.m. today, the 9th (Sat), a tropical depression developing in the sea east of the Philippines became Typhoon No. 23 (Trazi).
Around the same time, a tropical depression developing near the Marshall Islands changed into Typhoon No. 24 (Manny).
Currently, these typhoons are moving westward.

#Typhoon No. 23 9:00 PM, Saturday, 9th
===================
Center location East of the Philippines
Movement speed West 30km/h
Central pressure 1000 hPa
Maximum wind speed 20 m/s (near the center)
Maximum instantaneous wind speed 30 m/s
====================

#Typhoon No. 24 9:00 PM, Saturday, 9th
====================
Center location Marshall Islands
Movement speed Northwest 20km/h
Central pressure 1004 hPa
Maximum wind speed 18 m/s (near the center)
Maximum instantaneous wind speed 25 m/s
=================================

Typhoon No. 23 is expected to move westward and temporarily become a storm area around 9 p.m. on the 10th. It is then expected to make landfall on the Philippine island of Luzon on the 11th and pass through the South China Sea.

image

Typhoon No. 24 is expected to move westward through the Marshall Islands and reach the waters off the Mariana Islands by the 12th. It is not expected to develop into a typhoon, but is expected to turn into a tropical depression near the Mariana Islands on the 12th.

image

This is the first typhoon to form in five days since Typhoon No. 22, which occurred on the 4th of this month. This is the second and third typhoon to form this month. It is rare for three typhoons to exist simultaneously in the southern ocean.

At this time, Typhoons No. 23 and No. 24 are not expected to have much of an impact on the area around Japan.
Typhoons form, approach, and make landfall less frequently after November, but it is not uncommon for typhoons to form in November. There have been cases in the past where a typhoon made landfall in November (Typhoon No. 28, which made landfall in Wakayama Prefecture on November 30, 1990).
Please keep an eye out for future updates.








In addition to the powerful Typhoon No. 22, Typhoons No. 23 and No. 24 are also likely. There is a possibility of a triple typhoon in November.


2024/11/09 14:39

TOPICS IMG

As of noon today, Saturday the 9th, strong Typhoon No. 22 is moving westward in the South China Sea.
It will maintain its strong power and slowly move westward in the South China Sea until tomorrow, Sunday the 10th, then change course to the southwest in the South China Sea on Monday the 11th, and is expected to turn into a tropical depression in Vietnam on Tuesday the 12th.
It will move away from Japan and will have no impact on Japan.

As of noon today, Saturday the 9th, two other tropical depressions, which are the eggs of typhoons, have formed in the South Sea, and the Japan Meteorological Agency has announced that they are expected to develop into typhoons within 24 hours.

image

Tropical Depression B is moving westward east of the Philippines.
It will develop into a typhoon east of the Philippines at noon tomorrow, the 10th (Sunday).
It is then expected to pass over Luzon Island in the Philippines and move westward through the South China Sea on the 14th (Thursday).
There will be no direct impact on Japan.

Tropical Depression C is moving northwest through the Marshall Islands.
It will develop into a typhoon near Minamitorishima Island around the time the date changes tomorrow, the 10th (Sunday).
It is then expected to move westward near Minamitorishima Island and turn into a tropical depression in the Mariana Islands on the 12th (Tuesday).
There will be no direct impact on Japan.

If these tropical depressions develop into typhoons as expected, they will be called Typhoon No. 23 and Typhoon No. 24, respectively, and there will be three typhoons this month.
The average number of typhoons in November is 2.2, so the occurrence of typhoons is not uncommon.
However, at this time when the number of typhoons is decreasing, it would be a rare situation if three typhoons, Typhoon No. 23 and No. 24, existed at the same time as Typhoon No. 22.

In addition, in addition to Typhoon No. 22 and the two tropical depressions, there is a low pressure area in the southern seas, and there is a possibility that a new tropical depression will form.
We still need to keep an eye on the southern seas.








Heavy rain special warning issued for Amami Islands; unprecedented heavy rain; maximum vigilance against landslides and flooding in low-lying areas


2024/11/09 13:23

TOPICS IMG

A special heavy rain warning has been issued for Yoron Town in the Amami region of Kagoshima Prefecture today, the 9th (Sat).

In Yoron Island in the Amami region, the amount of rainfall (preliminary value by AMeDAS) from the start of the rain (4:00 p.m. on the 7th) to 11:00 a.m. today, the 9th (Sat) was 609.5 mm, exceeding 600 mm.

This is heavy rain that has never been experienced before, and there is a high possibility that disasters have already occurred, which corresponds to alert level 5.
Please be on maximum alert for landslides and flooding of low-lying land.

In the Amami region, warm and humid air circulating around the edge of the high pressure system is flowing in, making the atmospheric conditions very unstable.
As a result, there will be some areas where very heavy rain accompanied by localized thunderstorms will fall from around noon today, Saturday the 9th, to the evening of today, Saturday the 9th.

In addition, cumulonimbus clouds will develop locally from late tomorrow, Sunday the 10th, and there is a risk of strong gusts of wind such as lightning strikes and tornadoes.

Predicted 1-hour precipitation today, the 9th (Sat) [Heaviest areas]
Amami region: 50 mm
Predicted 24-hour precipitation by noon tomorrow, the 10th (Sun) [Heaviest areas]
Amami region: 150 mm

Today, the 9th (Sat), through the evening, be on high alert for landslides and flooding in low-lying areas, and be on high alert for rising rivers and flooding late tonight, the 9th (Sat).

If landslides and flooding have already begun, evacuation may be even more dangerous.
In that case, please move to a safe place, such as the second floor or higher of your home, or the other side of a slope.
