UPDATE WEDNESDAY: MetSul.com (you can translate automatically to English with Google Toolbar) is continuing to issue breaking weather updates with new satellite images. They are calling the system a Tropical Cyclone this morning while we are awaiting NOAA's update.
A subtropical cyclone, one of only 6 in recorded history, is affecting southeast Brazil today. There is some argument as to whether or not it has or will come on shore (see below) but it is causing high waves, winds and heavy rain. Below is a visible satellite from late this morning courtesy NOAA (alternate view):
"A SUBTROPICAL CYCLONE LIES OFF THE SOUTHERN COAST OF BRASIL...WITH AN ESTIMATED MINIMAL CENTRAL PRESSURE OF 1003 HPA...AND MAXIMUM SUSTAINED WINDS OF 25-34KT. DEEP CONVECTION IS WRAPPING AROUND THE CLOSED CIRCULATION...AND WITH SEA SURFACE TEMPERATURES OF 26C...THIS SYSTEM MIGHT MAKE THE TRANSITION TO A TROPICAL CYCLONE LATER THIS EVENING/EARLY MORNING HOURS. THE LOW LEVEL CIRCULATION...HOWEVER...WILL REMAIN NEARLY STATIONARY WHILE MEANDERING OFF THE COAST OF BRASIL THROUGH 48-54 HRS"
Here is a high-res visible satellite shot from earlier this morning courtesy the Navy. The only buoy in the area is not transmitting wind or wave observations but the WaveWatch model indicates (see above) that waves are over 18 feet offshore and a foot onshore.
Metsul.com says (translation provided by Google Toolbar):
"It was evening now featured in television news: "cyclone reaches the coast tonight." Not enough, is already on the coast. The image of a cyclone to the coast during the night, for those who live on the North Shore refers to the memory of the night of 27 to 28 March 2004, when Catarina touched the ground. This will not be a night of Catarina. The subtropical cyclone is not even a very deep system, which means less potential to bring severe weather. We're talking about a low of more than 1000 hPa and Catherine now had 970 hPa. The subtropical cyclone... originated from a low pressure system off the coast of the Southeast. The coastline may have maximum gusts, on average, 50 to 80 km / h, occasionally higher in the next 24 hours, but in the open sea, the greater distance from the coast, is that the wind should be stronger gusts that could exceed 100 km/h (62 mph)."

This storm didn't qualify as a "bomb cyclone" like the one in March, but it sure had some crazy weather.

Next week's cold outbreak is not unlike the ones in early March 2014 and 2015 but not quite as severe.

It's time to update my list of world wind records again after a massive storm swept Hawaii's highest mountain.
