Well, a tropical depression. Specifically, Tropical Depression 06W.
As per the National Weather Service:
TROPICAL DEPRESSION 06W IS EXPECTED TO CONTINUE ITS NORTHWEST MOTION OVERNIGHT AND WEDNESDAY...PASSING ABOUT 150 MILES SOUTHWEST OF GUAM AROUND 5 AM WEDNESDAY MORNING. AS IT DOES...BANDS OF HEAVY SHOWERS AND THUNDERSTORMS WILL MOVE THROUGH THE MARIANAS AT TIMES...BRINGING WINDS OF 20 TO 25 MPH WITH GUSTS AS HIGH AS 35 MPH. BY WEDNESDAY EVENING TOTAL RAINFALL OF 4 TO 6 INCHES CAN BE EXPECTED...WITH LOCAL FLOODING AT TIMES ON ROADS AND IN POOR-DRAINAGE AREAS.
Lucky for us it formed pretty close to us, which means we'll get wind and rain but that it shouldn't be anything too damaging. Not so for China, the Philippines, or Japan, one or more of which usually get hit by these things after they pass us. For example, Typhoon Bilis, which has killed 177 people thus far in China, destroying 19,100 houses and forcing the evacuation of more than 519,000 people. That was a tropical depression for Guam last week, which gave us a bunch of rain and stirred up some nasty surf, resulting in the death of a teen boy who was swept off the reef.
When these things form out around Chuuk, they often can turn into tropical storms or typhoons that end up hitting us, or passing close by enough to really fuck things up and disrupt lives and destroy stuff. Knock on fucking wood.
This was what the weather was like at 2 p.m. Tuesday afternoon, as I drove back to work. It got a little worse as the day wore on, and will be even worse in the morning hours. Weather MIGHT get a little better around Thursday or so.
For most of you across the United States ... enjoy your heatwave.
