However, the treatment of that water, she told CBS News, is something she "never had full trust and confidence in." And thinking that we're supposed to get 12 to 15 inches of rain, they are not seeing this to be a huge problem," Fried said.įried said the department informed her that the water has been partially treated, so that even if there is an overflow, "it won't be of issue." "Based on the water that is currently in Piney Point, they can sustain about 25 inches of rain. The issue resulted in millions of gallons of wastewater ending up in Tampa Bay and helped contribute to a devastating months-long red tide event.įlorida Agricultural Commissioner Nikki Fried told CBS News on Tuesday that she had spoken with Florida's Department of Environmental Protection earlier in the day and that they do not foresee Hurricane Ian being "a huge problem," given its current forecasts. The site made headlines last year when a massive leak was detected in the liner of a gypsum stack. Piney Point, a former phosphate mining facility in Manatee County, Florida, is undergoing 24-hour surveillance ahead of Hurricane Ian, CBS News has learned. ET Tuesday in Cuba's Pinar del Rio province, where officials set up 55 shelters and evacuated some 40,000 people. The storm battered Cuba with high winds and life-threatening storm surge on Tuesday, knocking out power to the island. It will approach Florida's west coast as an "extremely dangerous" hurricane, the National Hurricane Center said. Ian moved over the southeast Gulf of Mexico on Tuesday and passed west of the Florida Keys early Wednesday morning. Do not return yet if you have evacuated." "You need to continue to heed the warnings that are in place for Pinellas, Tampa, Manatee, Hillsborough. There is still going to be a storm surge event in the Tampa Bay region," Florida Director of Emergency Management Kevin Guthrie said Tuesday. "It's important to say that Tampa Bay region, you are not out of the woods yet. Millions of people were under mandatory and voluntary evacuation orders. Petersburg had looked set to for their first possible direct hit by a major hurricane in a century, but the latest forecasting models predicted Ian making landfall further south along the coast. Hurricane Ian gained strength in the Gulf of Mexico early Wednesday, developing into a Category 4 storm expected to make landfall along the southern portion of Florida's west coast late Wednesday. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.Follow Friday's latest developments here. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
