The Bureau of Meteorology has issued its fortnightly ENSO wrap-up, so I've updated the sidebar. It remains on "watch" status.
Strong trade wind reversal
One thing it mentioned was Tropical Cyclones Pam and Bavi (Bavi was rated at TC1 by BoM). Below is an image I posted from Earth wind map, in an earlier article. (My annotations.) Bavi is above the equator and Pam below.
Here is what was written by BoM:
In the western Pacific, severe tropical cyclone Pam and tropical storm Bavi* straddled the equator, producing one of the strongest reversals in the trade winds in recent years. This change is expected to increase the already warm sub-surface temperatures currently observed in the tropical Pacific Ocean, which may in turn raise tropical Pacific Ocean surface temperatures in the coming months. However, it remains too early to say whether the reversal in the trade winds is a short term fluctuation or the beginning of a sustained trend.
Tropical Cyclone Nathan
TC Nathan is on the map above. It's still going strong. It moved east away from the Queensland coast but has done a

Here's the track from BoM:
Nathan is expected to be a Cat 3 cyclone at landfall, which isn't the worst, but will be bad enough. The Bureau warning is not just about the winds and rainfall, it also mentions the likely storm surge.
Stay safe, everyone.
As Frank D said, the cyclone has intensified further. It's also swinging about a bit. Here is the track from BoM (updated with latest), together with the previous ones as above (animated). Click to enlarge.
