Tropical Cyclone 08S (Eric), marked with a red cross to the East, has lost a significant amount of deep convection over the past 12 hours due to sustained land interaction with the eastern coast of Madagascar, as well as interaction with Tropical Cyclone 09S (Fanele), to the West, in the Mozambique Channel.

The two systems are now less than 400 nautical miles apart – well within the threshold for direct cyclone interaction.

However, this interaction is expected to have little to no influence on TC08S beyond sustaining an already weak system.

Eric remains a minimal cyclone with sustained surface winds near 35 knots. Maximum significant wave height is 12 feet.

As the system begins to accelerate polweard ahead of the transitory mid-latitude trough to the  south, the system will be less vulerable to weakening by the other cyclone and land, and will intensify ahead of the trough under increased poleward outflow.

Around 27S sea surface termperatures drop below 26 degrees Celsius, which will again promote weakening as the cyclone beings to interact with a baroclinic zone and undergo extra-tropical transitioning (XT). Eric will complete XT transitioning within 12 hours.
