Unusual storm track could bring tropical storm to southern California:
The Category 4 storm, named Hilary, is predicted to first make landfall in Baja California, a Mexican state, on Saturday morning.

Forecasters say it will then lose wind speed and become a tropical storm, tracking north-west towards southern California, Nevada, Arizona and Utah.
The National Weather Service (NWS) said the potential for heavy rain, ranging from 3-6in (7-15cm) in some areas, and up to 10in in others, could lead to "significant and rare" impacts for parts of southern California and southern Nevada.

In San Diego, the NWS has issued a warning for the "high potential" of flash flooding.
But it is "exceedingly rare" for a tropical storm to come off the ocean and make landfall in California, Stefanie Sullivan, a forecaster with the National Weather Service in San Diego, told the New York Times.

The last time a tropical storm made landfall in southern California was in Long Beach in 1939.

A major hurricane, but a relatively unpopulated area of Florida:
The overall damage is still being assessed, but up and down the coast there is the sense that Idalia could have brought much worse destruction.

By Wednesday night, more than 225,000 people were still without power in Florida, and another 230,000 were in the dark in Georgia.
Coastal and inland flooding is expected in parts of Georgia, as well as South Carolina and North Carolina, as the storm makes its way along the south-eastern US coast on Thursday.
 
The South Atlantic is not known for cyclones (wind storms), but extra-tropical cyclones can cause severe flooding:
More than 300 mm (11 inches) of rain hit the state in less than 24 hours, triggering floods and landslides, officials said.

Massive amounts of rain following a cyclone in Queensland:
Record rainfall is causing widespread flooding in far north Queensland, in what authorities expect will be the Australian region's worst-ever flood.
Extreme weather driven by a tropical cyclone has dumped a year's worth of rain on some areas.
The city of Cairns has received more than 2m of rainfall since the weather event began.
 
Extreme waves from California winter storm:
Forecasters have issued warnings of more danger ahead after a rogue wave swept pedestrians off their feet and swamped a hotel in Ventura, Santa Cruz.

The National Weather Service (NWS) warned of "extremely dangerous conditions."

"Powerful waves and life-threatening rip currents pose an exceptional risk of ocean drowning and damage to coastal structures."

There is still quite a lot of uncertainty in the 3-day outlook, with this morning's models predicting higher peak intensity, and passing much closer to Reunion than Mauritius:

TC 02S has officially been named Belal. The long-term trajectory is quite curved, with somewhat slower passage, and affecting both Reunion and Mauritius in the same track!
