The savings bank may be blocking online banking customers for security reasons. They may have detected suspicious activity on certain accounts and are taking precautionary measures to protect their customers' funds and personal information. Additionally, the bank may be conducting routine maintenance or updates to their online banking system, temporarily restricting access to ensure a smooth and secure user experience once the maintenance is complete. It is also possible that there may be technical issues or glitches with the online banking platform that need to be resolved before customers can access their accounts again. **

Savings bank transactions can typically be deleted by accessing the account statement or transaction history on the bank's online portal or mobile app. From there, you can select the specific transaction you wish to delete and look for an option to remove or delete it. If you are unable to delete the transaction yourself, you can contact your bank's customer service for assistance in removing the transaction from your account history. It's important to note that some transactions may not be able to be deleted, especially if they are already processed or finalized. **

It is important to stay calm and seek shelter immediately if you suspect a tornado. Look for signs such as a rotating, funnel-shaped cloud, a loud roaring sound, or debris being lifted into the air. It is always better to err on the side of caution and take shelter in a safe location until the threat has passed. If you have access to a weather radio or smartphone, you can also check for tornado warnings in your area. **

To use online banking with your savings account, you will first need to set up online banking with your bank. This usually involves creating an online account and linking your savings account to it. Once your account is set up, you can access your savings account online to check your balance, transfer funds, set up automatic transfers, and even pay bills. Online banking provides a convenient way to manage your savings account from anywhere with an internet connection. **

A tornado forms when warm, moist air at the surface meets cool, dry air aloft, creating instability in the atmosphere. This instability causes the air to start rotating horizontally. If winds at different altitudes change speed or direction, this rotating air can be tilted vertically, forming a rotating column of air. As the column of air continues to rotate and intensify, it can develop into a tornado, with strong winds and a funnel cloud extending from the base of a thunderstorm. **

I'm sorry, I cannot provide real-time information on weather events. It's best to check with local news sources or weather authorities for the most up-to-date information on tornado sightings. **

It is not possible for an individual to build a tornado. Tornadoes are natural weather phenomena that form when certain atmospheric conditions come together, such as warm, moist air colliding with cool, dry air. These conditions are beyond human control and cannot be artificially created. Tornadoes are powerful and destructive forces of nature that should be respected and prepared for, rather than attempted to be built or manipulated. **

One can recognize a tornado by looking for certain signs such as a dark, greenish sky, large hail, a loud roar similar to a freight train, and a rotating, funnel-shaped cloud descending from the sky. Additionally, one may notice a sudden change in wind direction and intensity, as well as a persistent, low-lying cloud base. It is important to seek shelter immediately if any of these signs are observed, as tornadoes can be extremely dangerous and destructive. **
