Reporter survey teams need two more days to complete their review but the first storm isnt waiting for them. Be prepared to leave at very short notice and stock up on supplies. You may be trapped behind a bridge or culvert. Reporter because of the steepness of the terrain, some say a downpour lasting just 15 minutes could be enough to trigger a mudslide.

Youre watching nbc bay area news with the bay areas biggest Investigative Unit holding the powerful accountable. Nbc bay area, we investigate. Okay. Tonight theres a new twist in an unusual legal fight. It involves money, unpaid taxes, and a lot of marijuana. A san jose marijuana shop has refuses to pay the citys business tax for years and now ready to strike a deal though but lawmakers may not be willing to take the money. Our Investigative Reporter is with us to explain. Reporter guys this all centers around why account shop decided not to pay taxes in the first place. According to the federal government, possessing and certainly selling marijuana even for medical purposes is illegal. But at the same time, 26 states have laws on the booksing that allow the medicinal use of marin marijuana including california. That led to a bitter fight in san jose and over 1 million hang in the balance. David armstrong proudly grows all this marijuana. He runs a pot shop in san jose. But for the past four years, hes openly refused to pay the citys 10 business tax required of all medical marijuana shops. He owes at least 1. 3 million. So why is he stalling . He believes paying his taxes could actually land him in prison. I wasnt going to pay a tax that breaks state and federal law and be looking at ten years to life. Thats the offer we made to the city. Armstrong and his legal team believe paying the tax would mean theyre admitting to selling marijuana which is still illegal under federal law. So they sent this offer to the city of san jose. Its willing to pay that 1. 3 million with a catch. The deal says the money will not be labeled as a tax. But instead, a contribution. And the citys right to randomly inspect the shop would also have to end. Do you see any problems with the offer. I think theyre concerned. Reporter Richard Doyle is the City Attorney for san jose. You dont want to send a message that you dont have to play by the rules. One way or another, well try to get the money. Reporter doyle says the courts have already sided with san jose. In july a judge ordered them to pay up. The pot shop has since appealed to the California Supreme Court but a decision still hasnt come down. To say there is continuing resources and everything spent by the city is out of consideration, it always is. You dont see this as a matter of if they have to pay, but when . I think we have the upper hand. David ball is a law professor at Santa Clara University and specializes in marijuana regulations and policies. Right now, we really are speaking out of both sides of our mouth. The state is saying its okay and the federal government is saying this is not okay for people to use and theres been really no attempt to reconcile those two. Reporter but the professor believes mehdi marts argument still doesnt pass the smell test. As long as they admit theyre enabling other people to possess marin, that exposes them to criminal liability. Not paying the tax doesnt leave them more protected . The only way they can protect themselves from federal prosecution is by not engaging in any possession of marijuana at any point. Reporter so in choosing not to pay the tax, theyre just left even more vulnerable because now theyre breaking local laws. Thats right, thats right. Reporter lawyers for the pot shop disagree. This attorney believes san jose is playing a dangerous game of semantics. Our position is that if the tax were awarded differently, if it were for different reasons, theres no problem. But the word sales is in there. The word business is in there. Its a matter of characterization and a matter of what its for. Reporter san jose believes its owed even more money because of the penalties and interest that accrued. The city council will likely decide whether to accept armstrongs deal or keep fighting him in court. If youre asking me to break the law, state and federal law simply so you can collect a tax on a sale or a transaction of a controlled substance, we simply cant do it that way. Reporter while federal law bans the use of marijuana, the federal government did issue a set of guidelines that say prosecuting someone isnt likely if theyre following local laws and regulations. In fact, of the 16 pot shops in Good Standing right now in san jose, the city tells us none have ever faced prosecution from the feds for paying their taxes. In the meantime, voters in nine more states could decide to legalize marijuana when they head to the polls, guys, next month. Its a big election.

When we see it on the map, thats where the storm ranger is pistons. Its indicated by a red sweep. As that sweeps around, its going to give us much higher detail than any other Doppler Radar in the bay area. When the storms move in, it certainly is accurate to say it will be the most accurate. As we get a look right now at storm ranger, we have it located at mt. Allison here in the south bay. You can see the Doppler Radar hoisted up in the back. Thats active right now. Its also equipped with cameras and a weather station, as well including a x band radar to give us an idea where smoke is heading from wildfires. Lets take you into the weather maps. Youll see in the radar picture right now, the storm system is located off to the north. Thats where our heavier rain is and eventually, it will get here. The timing has slowed down. Thats the big update for us as we move into the bay area, storm ranger is active. We saw it in the picture. Its scanning around. You can see the red sweep right here. Were not finding any rainfall just yet but its in a perfect position tomorrow as that storm moves to the south to give us that rain data. As we get you into the morning forecast, we can expect the best chance of any kind of rainfall at least for the commute to be in San Francisco in the north bay. Check this out. With the storm slowing down, it looks like the south bay may have a fairly dry commute tomorrow but the clouds will be in and 58 degrees. Lets get right to the time line. You can see 8 00 in the morning, its centered across marin, napa and sonoma counties. Possibly some rainfall for the peninsula. Note a lot of the east bay and the south bay again potentially here dry. It will be a slow push to the south so even by 10 00 a. M. , its still mainly east bay and the peninsula. Eventually, heres where the slow down in the timing is coming in, noon to 1 00, well start to see a lot of the south bay get in on what would be some measurable rainfall. But well have to watch out in san jose for a little bit of a rain shadow effect as the Santa Cruz Mountains will steal a lot of the moisture so certainly totals not as high in san jose. Heres how it plaz out. A half inch to one inch from San Francisco northward. And then you can see san jose to gilroy quite a bit less here in terms of totals. Lets get you into the extended forecast. For saturday well see another chance of rain by the evening. It looks like the rain will linger all the way through sunday. So when it comes to the wet weather, we have four chances here as we head throughout the next couple of days. The main focus again is tomorrow mornings commute. Anyone in marin, napa and sonoma counties heading to San Francisco, thats going to be the worst commute for us as we head through 5 00 a. M. And 8 00 a. M. I see a lot of sunshine next week. 80 by next wednesday and thursday. Thanks, jeff. Still ahead, a doctor lashes out at a Major Airline over a midair emergency.
