Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE storm (name VARCHAR, max_speed VARCHAR, storm_id VARCHAR)
TABLE: CREATE TABLE affected_region (storm_id VARCHAR)

### Question ###
What is the storm name and max speed which affected the greatest number of regions?

### Accurate SQL ###

SELECT T1.name, T1.max_speed FROM storm AS T1 JOIN affected_region AS T2 ON T1.storm_id = T2.storm_id GROUP BY T1.storm_id ORDER BY COUNT(*) DESC LIMIT 1
