One of the big hotels had flooding in their cesspool which drained into the ocean in Kihei

So, what I heard from a fellow snorkeler was that you cannot safely snorkel, go into the ocean or surf or scuba dive right now from about McKenna Beach to hiway 30 at the very least if you want to be safe from bacteria in the cesspool that made it into the ocean from a large hotel there from flooding.

It rains a little every day (usually at night a lot) on all the Hawaiian islands. But, because it is usually this time of year above 80 degrees (at least during the day) and often above 90 degrees with full humidity the rains if you are dressed for it actually can be pleasant if you are wearing a T-shirt shorts and sandals or are barefoot in swimming trunks on the beaches or in the water. So, if you get rained on this time of year it is usually no big shakes. But, if you get too much in any one location of the types of monsoon rains with huge raindrops that are common here there often can be flooding, especially near or in a rain forest if you are in or near one.

For example, if you actually want to die just drive to Hana in a full cloudburst and your car could be washed completely off the road like almost happened to me and my family in 1989 when I lived here on Maui.

What happened to us then was that I was driving a ford window van with good ground clearance but as the cloudburst increased small rocks and boulders came off the little cliffs to our right on the road and were banging on our wheels on the right side of the van. When the rear wheels left the ground because of the flooding coming across from our right to our left and over a cliff into the ocean I yelled for the family to go to the rear of the van to jump up and down so their weight would bring the drive wheels back to the pavement maybe. This worked enough for me to get us out of that situation but we were all pretty scared then that we were done for and would be swept along with our Van into the ocean. But, luckily by the whole family jumping up and down in unison in the back of the van I got enough traction to get us out of there safely eventually. During all this water was coming under the right door of the van and washing across my feet on the gas and brake pedal it was flooding so bad then where we were. So, if you go on the road to Hana just remember in a big monsoon rain you can easily die there too in your rental car or truck so be aware where it is raining and how hard above you upslope towards Haleakala crater for your own safety.
