Mindulle is currently a strong tropical storm and strengthening is possible before it makes landfall over southern Japan early Monday morning, local time. Little wind shear combined with some very warm temperatures will continue to keep the storm in favorable conditions before landfall. Rain is already starting to move into southern Japan and will be approaching Tokyo in the next few hours. Storm surge with the storm will be between 3-6 feet near the center of the storm, from Shizuoka to Chiba, including Tokyo Bay. Rainfall amounts of 4-8 inches will be possible along the track of the storm, and as much as 12 inches of rain will be in the mountains of eastern Japan into Tuesday. Winds will also be gusting to 40-50 mph, including near Tokyo. The storm will quickly push off to the north and east Monday night into Tuesday, bringing the wind and rain into eastern Honshu and Hokkaido.

Tropical Storm Lionrock was about 340 miles east-northeast of Okinawa, Japan and moving southwest at 10 mph. Maximum sustained winds were 40 mph with gusts to 50 mph. Lionrock will continue to meander east of the Ryukyu Islands the next few days as it pushes slowly off to the west. The storm will continue to strengthen over the next several days and approach typhoon force as it moves near the southern Ryukyu Islands.

The storm is looking stronger over the past few satellite images as it continues to show increased convection and dry air is being pushed out of the storm. This, along with the warm water temperatures will allow further strengthening over the week. Rough surf will affect much of southern Japan and the eastern parts of the Ryukyu Islands as it spins.

The remains of Tropical Depression Kompasu will move over Hokkaido into Monday with some rain and winds. Rainfall of up to 4 inches is possible with the system and wind gusts should be under 40 mph with this, mainly on the southern and eastern coastline.

Lastly, an area of low pressure is located to the east of the Mariana Islands. As this low tracks to the northwest early this week, there is a small chance that it will become better organized, developing into a tropical system. Indications at this time are that this will pose no significant threat to land for the next several days.
