i attached a pdf file, i need the second one please. ill add a screenshot of the one i want. please provide clearly written answers.

his assignment will have you documenting the direction and intensity of tropical storms in the North Atlantic using data from the National Hurricane Center. You will initially track the storms from Arlene to Cindy. You will map the location and record the storm’s intensity based on the 11:00 AM and 11:00 PM updates (or nearest equivalent). Below are the steps to map and record named storms. For Part B of this assignment, you will continue to track storms throughout the season.
Visit the National Hurricane Center’s website: http://www.nhc.noaa.govLinks to an external site.
Click on ‘Archives’. Scroll down to ‘Tropical Cyclone Advisory Archive’ and press the ‘Go’ button next to 2022. Here you will find all of the updates and discussions for storms. You are responsible for the updates from 11 AM and 11 PM, for all named storms. Please be aware, some storms cross into other time zones. For those storms, you will be responsible for the 10 AM and 10 PM updates.
Select the storm. Click on either 11 AM or 11 PM. It will bring up the discussion.
Read through the discussion. Look for details such as shear, pressure, and temperature.
Next, go to the Public Advisories and select either the 11 AM or PM update. This will give you the Latitude and Longitude, wind speed, pressure and storm strength.
Use the Latitude and Longitude to map the storm on your North Atlantic Map.
When mapping the storm, make sure to use the correct symbol for the storm’s strength (Depression, Storm, Hurricane, Post-Tropical Cyclone, or Remnants). The symbols can be found on the home page at the bottom of the National Hurricane Center tracking map. Also, please label the storms with at least the first letter of their name and, if possible use different colors for the storms.
On the given table record the latitude, longitude, and max wind speed for each time (11 AM and 11 PM) and date.
