Lots of lightning around the eye of Severe Tropical Cyclone #Fina as it approaches the North Kimberly WA coast.
It is unusual to see this much lightning in such a strong system. Typically it indicates intensification in weaker systems. #CycloneFina #TCFina

A significant convective flare from near the LLCC of #TCFina indicates intensification. I would not be surprised if it is back to Cat 2 (Aus scale) strength in the next bulletin.

Tropical #CycloneFina over the last few hours showing a partially exposed LLCC in a dry slot between two blobs (technical term) of convective wet air.

A trough in the Indian Ocean south of Java is expected to slowly migrate Eastwards over the next few days and could develop into a tropical low early next week.
While the chance is low at the moment, it is the first I've noticed for this 25/26 season for Aus which is makes it newsworthy!

Quite the little cut off low is expected to form off WA over the next few days! #WesternAustralia #AusWx #WAWx

Check out that poleward outflow. 😮

2 years ago today Severe Tropical Cyclone Lola (01P 2023) was heading towards Vanuatu.
STC Lola was the strongest off season cyclone in the southern hemisphere. It peaked at 115 kt susustained (10min) maing it a Cat 5 (aus) / Cat 4 SS.
Tragically 4 people were killed and it caused >US$300M damage

Some of the hurricane specific models show a massive rain event for Jamaica & Cuba. This wobbly head-spinny one from HMON is a good example! #Melissa

🌀This bubbling mess that is Tropical Storm Melissa could develop into a major hurricane in the coming days.
It is predicted to be very slow moving dumping enormous quantities of rain over the Caribbean. #Watching

A lovely little low pressure system, leaving a cold pool of open cell convection in its wake, slipped to the South West of Western Australia this morning. 😍
