Tropical Cyclone 10S is located approximately 127 NM northwest of Learmonth, Australia

 

Northeast Pacific Ocean: There are no Tropical Cyclones

The last regularly scheduled Tropical Cyclone Activity Report of the 2024 eastern North Pacific Hurricane Season has been issued. Routine issuance of this section of the PDC product will resume on May 15, 2025. During the off-season, Special Tropical Weather Outlooks will be issued as conditions warrant by the NHC.

South Indian Ocean

Tropical Cyclone 10S

According to the JTWC Warning number 9, sustained winds are 95 knots, with gusts to near 115 knots

Animated enhanced infrared satellite imagery shows the system has rapidly intensified over the last six hours as evidenced by a more compact cold central cover that has developed a 15-nm pinhole eye.

The initial position is placed with high confidence based on the partly exposed llcc in the msi loop that was concentric with a defined llcc in the composite radar loop from the Port Hedland radar site.

Analysis indicates a highly favorable environment with warm sea surface temperatures, strong radial outflow, and low vertical wind shear.

TC Sean will continue track southwestward then southward around the northwestern then western periphery of the steering str.

The highly favorable environment will promote further intensification to a peak of 85 knots by 12 hours. Afterward, cooling sea surface temperatures, increasing vertical wind shear and dry air intrusion will gradually erode the system down to dissipation by 120 hours.
