Track of TS 14S

Tropical Cyclone Irina (14S), located approximately 470 nm east-southeast of Maputo, Mozambique, has tracked westward at 03 knots over the past six hours. The current intensity is estimated at 45 knots. Maximum significant wave height is 14 feet.

Recent animated infrared satellite imagery shows relatively shallow convection persisting over a compact low-level circulation center. tc 14s has maintained intensity over the past 12 hours under the competing influences of strong poleward outflow and a marginal sea surface temperature of 25 degrees celsius.

TC 14S continues to track westward under the steering influence of a low-level subtropical ridge positioned to the south. This westward motion is expected to continue through the forecast period. Passage over cool water and a decrease in upper level outflow will induce gradual dissipation below the warning intensity threshold of 35 knots by TAU 24.
